Poems from Astro Class

The terrestrial planets are small,
not very massive but dense,
close to the Sun and have few moons.
They have rocky outer parts and iron cores.

The Jovian planets are large, massive
but not very dense, far from the Sun,
and have many moons. They are
mostly liquid, but have rock/iron
cores. They rotate rapidly.
