Asteroids do not have an atmosphere. Comets do not have an atmosphere untill they approach the Sun at which point they do develop a (very thin) atmosphere.
comets become meteoroids when they pass through the earths atmosphere
Obviously it does have comets, astroids, and other things. Comets are astroids but when they enter the atmosphere of a planet, such as Earth, the astroids get so hot that the astroids turn into comets. Comets are made of ice and dust.
comets are found in the meosphere. this layer is quite cold. it can reach temperatures of -125
its because comets have ice in them, and that vaporises really quickly while the comet enters the earth's atmosphere.
Both meteoroid's and comets are made out of rock and burn up when getting into earths atmosphere.
these are comets
i don't think any comets have enough gravity to keep an atmosphere
Yes. Comets do not enter the atmosphere of the earth (we hope!). What you see is gasses that are released from the comet, illuminated by the sun. However, a meteor (shooting star) is visible only due to the atmosphere heating the meteor.
Most planets have an atmosphere, in addition to active comets and Saturn's moon Titan.
no, because the planet is a super thick atmosphere
No. They do not have enough gravity to hold on to the gasses.
it turns to dust.
caused by the sun after entering the sun atmosphere
No... they're far too small to support an atmosphere.
No, comets and meteors are not considered to be small planets. Comets are simply considered to be comets, and meteors are simply considered to be meteors. (Meteors are asteroids that have entered the atmosphere.)
No, comets have tails due to solar radiation subliming ices and other volatile substances into a temporary atmosphere that is tail shaped due to the comets velocity.
Comets are flying bits of rock that don't enter the earth's atmosphere and meteors are flying bits of iron stone or stony iron. Also meteors do enter the earth's atmosphere.
When comets come in contact with the earth's atmosphere, the air resistence and the action of gases wears it off, so ultimately it disappears.
comets can do this (depending on there make up) however this is rare as a comet is actually a satelite, it is stuck in a orbit. an asteroid burning up in the atmosphere is more likely, thiese rocks are not in orbit.
Those are the gases (atmosphere, if you like) that comet is carrying.
It's atmosphere is similar like ours on earth
