it would catch on fire from gamma rays or from solar flares.
i dont understand how a asteroid would be on fire in the vacuum of space? if this was on fire it would need an atmosphere meaning this would be a meteor not an asteroid
(correction on my first comment) if the asteroid was travelling that fast through space it would make a black hole and setsroy itself (only if the stars were the plsm. (another correction, on my sec comment) if the asteroid was travelling that fast (and didn't destroy itself) it would quickly escape th suns orbit on the first frame.
Also, it could catch on fire as it is close to a star, the solar fusion creates alot of oxygen, oxygen is larger than hydrogen and can therefore be 'made' by fusing hydrogen, this oxygen combusts undr the extreme heat and could burst out plasma, which collides with the asteroid and covers it in plasma (the plasma would be the same colour of the star it came off, so yes, you can have blue asteroids :D) sooooo yeah... (also, if you look closely at a tpt fusion you will notice there will be oxygen)
-_- If an asteroid IS travelling through space it would be going faster than light and would crumple into a minature black hole, essentially, colliding with itself and would completely disintergrate.
how did something that spelled asteroid wrong get on the front page?
Although, Leeazu is correct. At high enough velocities, there will be opposing forces, such as drag and friction that'll heat up the asteroid. The only problem is that Space is a near perfect vacuum, which means that air resistance (drag) and friction are near zero. Another problem is the low concentration of Oxygen in space. Therefore Leeazu is correct.
There is Oxygen in space. It's just that there's not a large enough concentration of O2 in space to support combustion. Also, temperatures are just about 2 degrees Kelvin above absolute zero. Fire needs a fuel source, oxygen and heat to survive. In space, there's no heat, so no particles can combust.
joe, shut up, I know it disintergrates and I know no oxygen in space, Did you see me type "In space only smoke or dust comes off the trail" And I forgot to say, some asteroids come in and hit the ground with no trace, usually medium - small meteorites. Don't shut other people down like that, and why would you laugh, I said no oxygen is in space, well, not litterally, there is almost no oxygen in space, thus its sparce and you could only find 1 atom of gas in a 10 cubic blocks of space.
