Our solar system includes the sun and eight planets that orbit around the sun the smaller, inner planets include mercury, venus, earth, and mars the inner planets are rocky and have diameters of less than 13,000 kilometers. ©2012happyedugator page 2 4 use the following website to learn about comets, asteroids, and meteoroids fill in the table below kidscosmosorg.
Any natural solar system object other than the sun, a planet, a dwarf planet, or a moon is called a small body these include asteroids, meteoroids, and comets most of the several hundred thousand asteroids, or minor planets, orbit between mars and jupiter in a nearly flat ring called the asteroid belt. How does our current understanding of the formation of the solar system account for the observation that all the planets orbit the sun in the same direction the sun itself rotates the counterclockwise orbital motion of the planets and the counterclockwise rotation of the sun descended from the original counterclockwise rotation of the solar nebula. The solar system is filled with a wide assortment of celestial bodies - the sun itself, our eight planets, dwarf planets, moons, asteroids and comets the earth is the only body in the solar system known to have life. Solar system formation scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova ) this explosion made waves in space which squeezed the cloud of gas and dust.
