That would depend on the asteroid, and on the comet. We don't know a whole lot about the structure of either; we've landed one space probe on an asteroid, and collided a refrigerator-sized impactor into a comet, but there are millions of each and we don't know if they are all similar. I suspect that they are not.
So the proper answer is "We don't know - yet."
Moons and comets appear to shine because of the light they reflect. Stars produce their own light.
Planets and comets shine because of reflected light because they do not produce their own light. Stars are enormous balls of gas that are undergoing fusion which releases a very large amount of energy in the electromagnetic spectrum which includes visible light. So stars shine because they produce their own light and not because they reflect light.
Meteors are just bits of dust, dirt or debris in space that enter Earth's atmosphere. They are often from comets. As they enter our atmosphere they burn up and fly through it. They look like stars shooting through the sky, hence the common names shooting stars or falling stars.
Objects that reflect light include planets, asteroids, and comets. The Sun emits light as it is a star. Meteors are visible as they burn up in the Earth's atmosphere, reflecting some light. Stars emit their own light through fusion reactions.
Comets, solar flares, asteriod belt, stars
Asteroids are also known as meteors, shooting stars, falling stars, bolides and comets.

Comets are falling rocks, whose paths can be calculated quite precisely.
Falling Stars happened in 2007.
Yes falling stars and shooting stars are meteors and meteorites.
Plants are normal and stars are like comets
comets
Comets orbit stars
Falling Stars was created on 2007-08-24.

new stars can get matter from old stars and comets really anything it can get its hands on
