What is the difference between a comet and an asteroid?
A comet is made mostly of ice, dust, and rock and develops a glowing tail when its ice vaporizes near the Sun, whereas an asteroid is a rockier or metallic body that does not typically form a tail. Comets also tend to follow more elongated orbits that take them far from and close to the Sun.
Why do comets have tails?
A comet grows a tail when it travels close enough to the Sun for the heat to vaporize its surface ice, releasing gas and dust into space. Solar radiation and the solar wind then push this material outward, forming the glowing tail that always points away from the Sun.
Do comets orbit the Sun like planets do?
Yes, a comet orbits the Sun, but unlike most planets its path is usually a long, stretched-out ellipse rather than a nearly circular orbit. This is why some comets are visible from Earth only once every few decades or even centuries.
