  1. Marked by a teacher

    My project this year is based on the solar system. In my project I will discuss the theory behind the start of the solar system. I will also describe the sun and planets moving round it.

    4 star(s)

    It is also possible that the planets were never a part of the hot Sun itself. They may have come from the remainder of an exploding star (supernova) that happened near the Sun. The planetary orbits are elliptical in shape and all lie in one plane except Mercury and Pluto whose orbits are tilted at an orbit of 7?and 17?. All the planets move the same direction. Asteroids and comets move in a completely different plane. Planets are recognised in the night sky because they shine with a steadier light than the twinkling stars.
