your mom which is Austin jung hahahahahaha
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.
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.
Yes
Nobody truly knows. It is likely that - as is the case for the Earth - any water was 'delivered' there by comets.
You shouldn't be afraid of comets because they are generally harmless and pose minimal risk to Earth. While they can be fascinating astronomical events, the vast majority pass safely at great distances from our planet. Additionally, scientists continuously monitor these celestial bodies, ensuring that any potentially hazardous comets are detected well in advance. Embracing the beauty and mystery of comets can inspire curiosity rather than fear.
Although comets contain water in the form of ice, scientists do not consider them a significant source of Earth's ocean water. Instead, the majority of Earth's water is thought to have originated from within the planet during its formation and through volcanic outgassing over time. Comets may have played a role in enriching Earth's water with isotopic compositions different from those found in the planet's interior.
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 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.
