What else can I help you with?
Is the earth any heavier now then when it started?
Yes. It is heavier through the bombardment by meteors, asteroids, comets, and another planet (which led to the formation of the Moon).
Will the next comet cause the coasts to flood within 100 miles inland?
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.
Is it possible comets may have any influence in the earths' weather or cycles even the orbit variances?
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.
Are any comet strikes a source of the ocean water?
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.
Does any comets ever pass earth?
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/
Would earth have any oceans if it weren't for impacts from comets from the outer solar system?
Yes
Why does Mars have water?
Nobody truly knows. It is likely that - as is the case for the Earth - any water was 'delivered' there by comets.
Why sould you not be afraid of comet?
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.
Are neutrinos dangerous to the earth?
Neutrinos are not harmful to Earth or its inhabitants. They interact extremely weakly with matter and pass through our planet as well as us without causing any harm. Millions of neutrinos pass through us every second without us even noticing.
How many comets does Mars have?
There are no comets that orbit the planet Mars. Comets, some, orbit the sun. Mars on the other hand does have two moons, Phobos and Deimos.
Which US city does the prime meridian pass through?
It doesn't pass through any US cities but it does pass through London, England.
Why are there so many meteorites near earth?
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.
