5e. Ask question to compare and contrast the characteristics, composition, and location of comets, asteroid, and meteoroids

Space Rocks

Our Solar System consists of various celestial bodies, such as comets, asteroids, and meteoroids.  

Comets

• A comet is a small, frozen mass of dust and ice that travels in elongated, elliptical orbits close to the sun, where they form a tail of gas particles pointing away from the sun.

What is inertia? 

• A force that attracts and repels objects.

Which space rock is made out of Ice?

Meteoroids

Meteoroids that have landed on Earth’s surface are called meteorites. Because comets, meteoroids and asteroids have smaller masses than planets and the Sun, their orbits are strongly influenced by the gravity of the planets as well as the Sun
