Where do comets orbit?
Oort cloud
Nebular model
A Mars-sized object collided with Earth causing it to lose part of its mantle which started to orbit the Earth
by collecting more material and growing bigger
Meteoroids enter Earth's atmosphere and burn up, meteorites collide with Earth's surface
As they near the sun, the radiation heats up the comet giving off gases in the form of a long tail
Large cloud of dust and gas in space
Stony
