Is this a good beginning paragraph for my 5th grade essay on whether i would rather visit the inner or outer planets (just a yes or no) Have you ever looked up at the night sky, scoped out a planet, and wonder what it would be like to visit one of them? Which would you like to pick, Mars or Neptune? Well to start you off, Mars is an inner planet (a planet whose orbit lies within the asteroid belt) and Neptune is an outer planet (a planet in which its orbits lie beyond the asteroid belt.) The inner planets consist of Mars, Venus, and Earth. The outer planets consist of Jupiter, Saturn, Uranus, and Neptune. They each consist of harsh temperatures, atmospheres, but if I had to choose between inner or outer, I would pick inner planets.
