Asteroids formed from left over materials from when our solar
system formed that never formed into a planet.
asteroids are NOT round they are bumpy and do not form a perfect sphere. One of the criterias of a planet is it has to be perfectly round
Asteroids are too small to have enough gravity to prevent any atmosphere form escaping.
Yes. Water has been observed on asteroids in the form of ice. At the near absolute zero temperatures of space and asteroids the ice would have little volatility.
by asteroids that hit the moon
asteroids formed from small pices of rock and metal just like the rest of te solar system
An asteroid is a small, rocky body that orbits the sun. Scientists now hypothesize that asteroids are remnants of the early solar system that came together to form a planet.
The densest form of interplanetary debris are asteroids. Asteroids are basically thick rocks that come together from the interplanetary dust and debris that sometimes fall to Earth.
Asteroids are big or small chunks of other planets that have been knocked off by other asteroids when they collide.
from small pieces of rock and metal
The asteroid belt did not form a planet because the asteroids do not have enough mass. Therefore the cannot create enough gravity necessary to attract other asteroids to create a planet.
They are formed by asteroids and meteorites crashing into the surface of the moon
Because they do not have volatiles in them to form a coma as to comets.
because the asteroids orbit close to the sun and every time they do they heat up which makeds them unable to join particles and form a planet.
They are actually called craters, they were formed by asteroids colliding with the moon.
