The ecliptic and the seasons - Solstice and Equinox - English version
For comments and suggestions (errors in the translation of subtitles, for example), enter on this page. Thank you. Thanks to Herald Soares de Oliveira (Brazil) for his help in translating subtitles in Portuguese. Teaching in Astronomy: http://www.pawean.com The ecliptic is a fundamental level in astronomy. In this first part, described the plane and its relationship with Ecuador and the seasons of the year. The Earth has a number of periodic motions. Of these, the most important because of its intensity are two: the rotation on its axis and the rotation around the Sun These movements originate cycles in which we are all immersed: rotational movement is what gives rise to day and night and lasts 24 hours; translational motion is the cause of the seasonal cycle, and lasts 365 days, ie one year. The reason of the seasons lies in the special provision of the axis of rotation of the earth. The imaginary red line around the Earth is Ecuador. Ecuador is a fundamental background in astronomy is adopted for calculation of position, both on the surface of the earth as in heaven. The coordinates calculated based on this plane are called "equatorial coordinates." The line of the poles is perpendicular to this plane, and is the line around which Earth rotates. If we make visible the plane of Earth #39;s orbit around the sun and project it into space until it intersects the globe, see that Ecuador does with Earth a 23 degree angle and a half. This is called "obliquity of the ecliptic" The ...From:Antonio Gonzlez EstvezViews:5 1ratingsTime:09:13More inScience Technology
