Mercury Venus Earth Moon Mars Asteroid belt Jupiter Saturn Uranus Neptune Pluto Comets Glossary |
People have been watching the sky for thousands of years and wondered exactly what is out there. With advances in telescopes as well as spaceships which have physically traveled to various planets, a considerable amount of knowledge has been obtained to better understand the universe near to us.
At the center of the Solar System is the
Sun. This is but one of billions of stars in the sky, but is
important to us as it gives us warmth and energy for us to use. There
are many worlds that are near the Sun, each of them are as different
as you can possibly imagine. All of these worlds that either orbit
the Sun or orbit a planet going around the Sun make up what we call
the Solar System. As you read each of the sections about these
different worlds, we will explore the differences between all of
these worlds, and hopefully you will understand how unique and
special the Earth is as well.
