Minor Objects in the Solar System

COMETS

Comets are close to the sun. The surface of the comet warms and gasses boil off carrying dust. The coma is made of gas and dust.It is sometimes called a dirty snowball. A comet loses material during each trip around the sun. When all gases boil off, solid material becomes either a meteoroid or asteroid. There are three parts of a comet: nucleus,coma,and tail. The tail is always facing away from the sun.

ASTEROIDS

Asteroids are classified as rocky and metallic objects that orbit the sun. They are too small to be planets. Most of them are in the belt in between Mars and Jupiter. Pluto was considered as an asteroid, but now it is called a dwarf planet.

METEOROIDS

Meteoroids are metallic rocks that float through space. They are smaller than asteroids. Also, they travel around the sun in an orbit.

METEOR

They are a streak of light in the sky from a meteoroid burning up up because of friction with gases in the atmosphere. They are sometimes called shooting or falling stars. About 3,000 metric tons of meteors fall as dust per day.

METEORITES

A meteorite is a meteoroid that reaches the surface of Earth without burning up. There are three types: stony, stony iron, and iron.
