No, the mass of the sun is to much for it to mean anything. A thousand comets could hit the sun all at once and it wouldn't do anything.

I'm not really an astronomer, but given the amount of comets out there I'd say it's probably pretty common, even though most of them simply burn up pretty early on.

Wanna see some real amazing pictures from 2000/01?
http://soho.nascom.nasa.gov/bestofso...T_Nov8_00G.gif http://sohowww.nascom.nasa.gov/besto...GE3/c2dblG.gif Beautiful! Many more under the 'Best of Soho' link on the site! 8)

I've heard all the planets together could hit the sun and it wouldn't be phased. The sun is just to dang big to care.

Great pics.........SOHO is a Great site. Although some use it to foolishly prove a false existance of PX. Myself on the other hand enjoy the pics as I have always been fascinated to the center of our Solar System. thanks; josun |

But… Should a high velocity solar collision with a significantly massive object (i.e. ~ 0.5 'Lunar masses' and up) occur at such position/attitude that Earth is 'splashed' by ejected plasma... OOOOOOOOOOOH! Golly! That'd smart!!!
Moreover, it is hypothesized (in certain quarters) that the 'swallowing' of large planets may be a factor in the enigmatic, transient, and rather dramatic (i.e. circa 1,000,000 fold) isothermal expansion observed of certain stars - But not to worry! Jupiter and 'his' buddies (i.e. the gas Giants) are content in their orbits ![]() "The sky is filled with good and bad the mortals never know..." --- Zep OBTW please don't be confused by the claimed 'sizes' of comets! - The coma (i.e. the gaseous cloud of volatilized substances surrounding many such bodies as they approach the inner solar-system and are hence heated by (far) IR and 'mechanically' [i.e. kinetically] and electrically 'opposed' by Particulate flux (i.e. Ions, HENs and, to a lesser extent, HEPs) may measure many times the diameter of Earth *HOWEVER* the mass is negligible - It is the *NUCLEUS* of a comet which is important in discussions of impact energy, perturbation, etc... (Comet nuclei typically measure 1 to 50 Km -10 Km representing an average - While Earth impact would be very, very 'bad' - a close encounter would be without sequela ![]() Please pardon the *ATROCIOUS* grammar apparent in this post! - My brain over runs me fingers (or, is it the converse?) Very Best Regards Dan Sarandon ![]()

Comets hit the sun quite often. Clearly they do not significantly affect the behavior of the sun. Asteroids occasionally hit the sun as well. There have been several SOHO observations of comets hitting the sun. Comets that we have observed range in size from a few kilometers diameter up to around 100 kilometers in diameter and the majority of comets hitting the sun may well be smaller than 1 kilometer, particularly in the debris from teh Kreutz sugnrazing comets which appear to be the debris from the breakup of a larger comet several thousand years ago. Comet SHoemaker-Levy 9 impacted Jupiter (which is very much smaller than the Sun) and other than some impact scares that lasted about a year, hardly affected Jupiter a bit.

If you're ever concerned about comets hitting the Sun, remember, the Sun is big and comets are tiny. I find it useful to scale down the local part of the universe by a factor of 1,000,000,000 to put things into context. If we do that: The Earth is about 1.27 centimetres in diameter. The Sun is about 1.4 metres in diameter, and is about 150 metres away from the Earth. The Moon is about 3 millimetres in diameter, and is about 40 centimetres away from the Earth. A comet would be maybe 0.01 millimetres in diameter, so compared to a 1.4 metre diameter Sun, would be of negligible importance. (Incidentally, on this scale, the nearest star would be about 42,500 kilometres away.) |

Melanie, if you really want to get a picture of the scale of the universe, I suggest going on the Solar System Walk. I did it myself last year, and it's quite humbling.

If anyone wants a good model of the solar system (and most of the Orion Arm of the Milky Way) check out this:
www.shatters.net/celestia a bit skimpy on information, but the eye candy is great.
