Document Summary
Two (earth and mars) have satellites and two do not: further away from the sun are 4 very large planets we term the jovian planets or the gas giants (jupiter, saturn, They are huge, low density, composed mostly of hydrogen and helium and many satellites: between the terrestrial planets and the jovian/gas giant planets is a band of small, rocky objects called asteroids, which together make up the asteroid belt. The largest object in the asteroid belt is called ceres; it is spherical, may even have an ocean and an atmosphere, but is just a tiny fraction of moon"s size: pluto, out past the gas giants. Larger objects in this region are being studied; a couple are called eris and sedna. This is likely the originating location of most comets that cruise through the inner solar system: finally, marking the outer limits of the solar system may be an enormous belt of icy bodies.
