What Is A Near-Earth Object (NEO)?

Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighborhood. Composed mostly of water ice with embedded dust particles, comets originally formed in the cold outer planetary system while most of the rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.

What Is The Purpose Of The Near-Earth Object Program?

The purpose of the Near-Earth Object Program is to coordinate NASA-sponsored efforts to detect, track and characterize potentially hazardous asteroids and comets that could approach the Earth. With over 90% of the near-Earth objects larger than one kilometer already discovered, the NEO Program is now focusing on finding 90% of the NEO population larger than 140 meters. In addition to managing the detection and cataloging of Near-Earth objects, the NEO Program office will be responsible for facilitating communications between the astronomical community and the public should any potentially hazardous objects be discovered.

How Many Near-Earth Objects Have Been Discovered So Far?

As of June 29, 2015, 12863 Near-Earth objects have been discovered. Some 872 of these NEOs are asteroids with a diameter of approximately 1 kilometer or larger. Also, 1597 of these NEOs have been classified as Potentially Hazardous Asteroids (PHAs).

What Are Asteroids And Comets?

Asteroids and comets are believed to be ancient remnants of the earliest years of the formation of our solar system more than four billion years ago. From the beginning of life on Earth to the recent spectacular impact of Comet Shoemaker-Levy 9 with Jupiter, these so-called "small bodies" play a key role in many of the fundamental processes that have shaped the planetary neighborhood in which we live.

Comets Claim Galaxy Cup After Downing Crunch

April 12, 2015 - American Hockey League (AHL) Utica Comets UTICA, N.Y. - In front of the 26th sold out crowd and final regular season game at The Utica Memorial Auditorium, the Utica Comets (45-20-6-2) claimed the Galaxy Cup for the second year in a row after defeating the Syracuse Crunch (41-23-9-0) 2-1 Sunday afternoon. With the victory, the Comets reclaimed the Western Conference's top spot with 98 points.

Rookie Hunter Shinkaruk (1-1-2), and Cory Conacher (1-0-1) both notched goals to carry the Comets to their 25th victory at home for the 2014-2015 regular season. Cal O'Reilly (0-2-2) also dipped his hand in the cookie jar by adding two more assists to his overall point total (59) for the season.

The Crunch were the first ones to find the back of the net in the first period and it was ironically just after the Comets had finished killing off their second penalty of the game. At 7:55 Brayden Point won the faceoff for the Crunch just to the left of Jacob Markstrom. Kevin Lynch received the loose puck and snuck in past the Comets defense as he backhanded it towards the crease and through Markstrom's legs for the one-goal lead.

No time was lost as the Comets scored early in the second period to tie it at one. O'Reilly and Bobby Sanguinetti took advantage of their power play situation and set up a nice play to get it to Shinkaruk who walked in front and backhanded it past Syracuse goaltender Kristers Gudlevskis for his 15th goal of the season at 4:45.

The Comets gained another chance on the power play just after the 13-minute mark and took advantage of the opportunity full-heartedly. Cal O'Reilly tallied his 49th assist of the season as he dished a pass to Cory Conacher just below the right point. With one swift swing, Conacher pounded it into the net for the Comets second power-play goal of the game and the eventual game-winner which put the Comets up 2-1 at 15:21. Shinkaruk also tallied an assist on Conacher's 10th of the season.

After playing 38 games at home this season, the Comets have compiled a 25-10-3-0 record, which helped them achieve their first place standing within the Western Conference with the addition of Sunday's two-points.

The Comets might be done at The AUD for the regular season but they still have three more games to go on the road. The Binghamton Senators will be welcoming the Comets back once again for their last meeting of the season this Wednesday at 7:05 p.m.

Three Stars: 1. UTI - Cory Conacher (1 Goal) 2. UTI - Cal O'Reilly (2 Assists) 3. UTI - Jacob Markstrom (20 Saves, Win)

Comets Claim Galaxy Cup After Downing Crunch

Edinburgh Monarchs too strong for Workington Comets

By Liam Waite

Published at 10:36, Monday, 13 April 2015

Edinburgh Monarchs 56 Workington Comets 37 Workington Comets League Cup campaign began in dismal fashion with a heavy 19-point loss at the hands of current holders Edinburgh Monarchs as they went down 56-37 last night.

Kyle Howarth

Their first taste of competitive action in 2015 didnt go as planned as star Kyle Howarth finished only one race and Comets took just two heat advantages all night.

But Comets team manager Tony Jackson said the score flattered Edinburgh and was happy with his riders efforts on a tough night.

He added: Overall were disappointed to lose but weve got to be realistic and this is a place where nobodys got anything for a long time.

We could put seven world champions in Workington jackets and they still wouldnt get anything around here.

We wanted to hit the 40 point mark and we would have had that if Branford hadnt fallen when we were on for a 5-1 in heat 12.

Howarth had mechanical problems all night but when he did get his bike going he beat Craig Cook so there you go, the luck just wasnt with us tonight but we put on a good show.

Bach crocked as Workington Comets lose cup tie in Glasgow

Published at 10:25, Monday, 13 April 2015

Glasgow Tigers 53 Workington Comets 38: Workington Comets were left to lick their wounds yesterday after a 53-38 defeat away at Glasgow Tigers and the loss of skipper Rene Bach.

Rene Bach

Team manager Tony Jackson admitted the result was disappointing and cursed his sides bad luck after Bach withdrew from the final third of the meeting with shoulder pain after a crash. It is not yet known whether the Dane will be fit to ride this weekend.

He added: Several times I was on the phone to the referee because Glasgow were getting away with some pretty blatant movement at the starts and getting off to flyers every time.

Heat 10 was the turning point and after we lost Rene it was a pretty difficult situation we were in.

To come here and win would have been a big ask given how well they go around here, they were tipped pre-season as one of the favourites in this league.

We would have liked to nick a point and were it not for losing Bach I think we would have had enough.

Comets won the toss and chose gates one and three for the opening heat, which saw a thrilling battle between Ricky Wells and ex-Comet Richard Lawson, with the former emerging the victor.

Heat two was stopped due to an issue with the tapes, with Comets reserve Nicki Barrett winning the re-run ahead of Victor Palovaara and James Sarjeant. Rafal Konopka, guesting in place of the absent Nathan Greaves, recovered from a poor start to pass first Palovaara then Sarjeant, before he fell while in second place on the final lap to turn a Comets 5-1 into another draw.

Pair of Comets Power-Play Goals Spell 2-1 Crunch Loss

April 12, 2015 - American Hockey League (AHL) Syracuse Crunch UTICA, N.Y. - The Utica Comets overcame a 1-0 deficit to defeat the Syracuse Crunch, 2-1, Sunday afternoon at the Utica Memorial Auditorium. Hunter Shinkaruk and Cory Conacher provided power-play scores in the second for the Comets who edge the Crunch in the season series seven points to six.

The regulation loss for Syracuse (41-23-9-0), coupled with a Hartford regulation win at Providence, drops Syracuse to second in the Northeast Division. The Wolf Pack's 39 non-shootout wins trump Syracuse's 38 to break a 91-91 points tie. Both teams have three games remaining.

Kevin Lynch garnered a first-period lead for Syracuse with his third goal of the season and second in four games. After a right-circle face-off, he charged the right goal line and slid the puck under Comets netminder Jacob Markstrom at 7:55. Brayden Point notched the lone assist, his first as a pro.

The Comets converted on two of their three second-period power plays. Seconds after Tanner Richard was called for holding the stick at 4:45, Shinkaruk snuck behind the Crunch defense, cut right across the crease and lifted a backhand shot past Kristers Gudlevskis to tie the score, 1-1. Cal O'Reilly and Bobby Sanguinetti assisted.

O'Reilly also had the primary assist on Conacher's goal 10 minutes later. The Comets captain has 22 power-play assists to lead the AHL and 59 points overall (10g, 49a). Shinkaruk collected the second assist on Conacher's 10th goal of the year, a right-wing blast after Jonathan Marchessault had trouble clearing the defensive zone.

Marchessault was returned to Syracuse by Tampa Bay earlier in the day after recording his first goal and assist for the Lighting Saturday vs. Boston. He had a game-high five shots Sunday, along with Ryan Martindale. The Crunch were held to six shots in the first, six in the second and nine in the third. Kristers Gudlevskis made 24 saves on 26 Comets shots, slipping to 25-13-3.

An altercation in the game's final seconds resulted in five misconduct penalties, two against Syracuse and three against Utica.

Syracuse was 0-for-3 on the power play while the Comets were 2-for-7.

The Crunch visit Albany 7 p.m. Wednesday. Syracuse is 6-1-0-0 against the Devils this season.

Success for Workington Comets rider Harrison in his own testimonial

By Liam Waite

Last updated at 10:29, Monday, 13 April 2015

Workington Comets legend Rusty Harrison won his own testimonial meeting in stylish fashion on Saturday as he went unbeaten as the fastest man on the night.

Rusty Harrison flanked by runner-up James Wright, third-placed Kyle Howarth and Christian Henry

The weather stayed cold and blustery but most importantly dry for the aptly named Rustys Didgeri Do, honouring the rider who has been a fan favourite at the Zebra Claims Stadium for more than 10 years.

Harrison, 33, said: It was a cracking night and just to finally get it on was a massive relief after so much work.

It was a dream come true to win it, I never expected that in a million years.

I would have been quite happy just to mix it up with the best of them so to go out and win the thing was just perfect.

Its just a shame it was a bit cold but after the problems we had in the past it was nice for it to stay dry and get going.

Harrison is currently in his 10th season in a Comets race jacket and is now second in the Comets all-time appearance table.

Comets Tripped up by the Senators in a Shootout

April 11, 2015 - American Hockey League (AHL) Utica Comets BINGHAMTON, N.Y. - It took extra hockey, a shootout to be exact, but the Utica Comets fell to the Binghamton Senators 3-2 Friday night at the Floyd L. Maines Veterans Memorial Arena.

Brandon DeFazio (1-0-1) and Hunter Shinkaruk (1-0-1) scored for the Comets, while Joacim Eriksson made 35 saves in the loss. Cal O'Reilly did not register for a point for the first time in 14-games, which is a 2014-15 season high in the American Hockey League.

After a scoreless first period, the Comets wasted little time in the second period. Off of a face-off to the left of Senators' goaltender Chris Driedger, Alexandre Grenier found Shinkaruk all alone in the slot for the game's first goal just 50 seconds into the period.

Cashing in on a Comets turnover, Cole Schneider ripped a shot over the glove of Eriksson to tie the game at 1-1.

With 8:13 left the Comets re-took the lead once again. On the power play, Alex Friesen sprung Brendan Gaunce and DeFazio in on a two-on-one. Gaunce sauced a pass over a sprawled out Senators' defender to DeFazio who one-timed it home. The goal was DeFazio's first goal on the road since November 21 vs. Rochester.

Skating four-on-four just over three minutes later, the game was once again knotted. A two-on-one opportunity for the Senators. Eriksson turned aside the original shot from Derek Grant, but Buddy Robinson was there to pop the rebound into the empty net.

After a scoreless third period and overtime, the teams headed to a shootout. The Senators scored in the second round, and that is all they would need to seal up the win.

The Comets will wrap up their three-in-three weekend tomorrow afternoon as they take on the Syracuse Crunch at the Utica Memorial Auditorium at 3pm.

Workington Comets confident ahead of League Cup clashes

Last updated at 11:18, Friday, 10 April 2015

Workington Comets season steps up a gear this weekend with a daunting League Cup double-header.

Laura Morgan

The west Cumbrian speedway clubs first competitive action starts with a tough trip to reigning Premier League and League Cup champions Edinburgh Monarchs tonight (7.30pm start) and they then journey to Glasgow on Sunday (3pm start).

However, Comets will be in confident mood after retaining the Ian Thomas Shield at the weekend thanks to a narrow victory, which was decided by a run-off, against Newcastle Diamonds.

Owner Laura Morgan said: Its a really tough start. You have got to start somewhere and sometimes its better to get the toughest out of the way.

At Redcar we had a good win and last weekend saw some brilliant racing from both sides, so we have got some track time under our belts.

Although Premier League glory remains the number one target, Morgan is also taking the League Cup seriously.

Comets reached the semi-final stage last season but bowed out after an 85-97 loss on aggregate to Peterborough.

Morgan added: The league is the number one we are looking at but the League Cup is definitely something we are targeting.
