Document Summary
The asteroid belt lies between mars and jupiter=between the terrestrial and jovian planets! Cosmology: study of the structure and history of the. Planet orbital planes lie within 3 degrees of the sun"s equator. Planet: is an object that orbits a star, is spherical, and has. Cleared it"s neighborhood of other objects (i. e. , planet"s gravity has pulled in all particles of matter in its orbit). Light and heat derives from nuclear fusion reactions. Requires thinking in unfamiliar scales of space and time. Heliocentric: sun-centered- proposed by the greeks ~ 250. Gravity binds stars together into vast galaxies. Kepler his elliptical planetary orbits refuted ptolemy. Newton planet motion explained by his theory of gravity. Solar system: a sun, planets, moons and other objects held together by the glue of gravitational attraction. Earth shares the solar system with 7 planets. Is a large solid body orbiting a star (the sun). Has cleared it"s neighborhood of other objects.
