Yes! All the time. Although comets tend to have very elongated orbits which bring them close to the sun which slingshots them far out into space and back again. NASA's Jet Propulsion laboratory has a great site for tracking objects in our solar system. solarsystem.nasa.gov/eyes/
your mom which is Austin jung hahahahahaha
There are hardly any comets, meteorites or asteroids near earth. There are only a few that are millions of kilometers from earth. There are a few that pass earth a bit closer because of the asteroid belt between Mars and Jupiter.
There are comets around all the time. In order to have this much of a cataclysmic effect, it would need to pass very close to the earth, if not hit it entirely. At the moment, we do not know of any comets on this trajectory.
Comets have a very low mass compared to Earth, so any affect they will have on Earth is from impacts which will affect the global weather.
Yes
I don't think any COMETS have struck the earth, but METEORITES have. Comets are icy balls of gas and dust that fly around the sun like Halley's comet.
Nobody truly knows. It is likely that - as is the case for the Earth - any water was 'delivered' there by comets.
You don't pass any. There' nothing in space between Earth and moon except maybe a few meteoroids. The planet that is able to come closest to Earth is Venus. When Venus is as close to Earth as it can ever get, it's more than 100 times farther away than the moon ever is.
There are no visible comets at this time.
NO
This question was posted on September 3, 2011, so the year 2010 is already in the history books. I don't recall any especially impressive comets in 2010. But basically, there are several new, never-before seen comets (or long-period comets last seen during the reign of the Pharaohs, like Hale-Bopp) for which we have no orbital knowledge, that appear each year. Once the comet has been seen three times, we can calculate an orbit, and determine, more or less, where it will be at any future date. But until then, it's a mystery.
Yes. It is heavier through the bombardment by meteors, asteroids, comets, and another planet (which led to the formation of the Moon).
