What else can I help you with?
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.
What are the characteristics of comets and meteoroids?
Comets are dusty pieces of ice and rock that partially vaporize when they pass near the sun. Meteoroids are pieces of rock, usually less than a few hundred meters in size, that travel through the solar system.
How quickly to comets cross your skies?
Comets can actually be visible in the sky for up to a few hours, depending on how close they actually get to Earth.
What comes from the sky and hits earth?
Few comets and meteoroids come from the sky and hit earth. or hail
Why do you rarely see comets?
Comets spend the majority of their time in the far reaches of our solar system, where they are not easily visible from Earth. They only become visible when they enter the inner solar system and are illuminated by the Sun, hence their rare appearances. Additionally, many comets have long orbital periods, further contributing to their infrequent sightings.
How many years does a comet orbits planet earth?
Comets don't or it the earth, they are in long irregular orbits around the sun. These orbits can range from a few years to thousands of years.
What was the last comet to be seen from earth?
It's impossible to answer that, but I can tell you whenit was seen: right now.There are nearly always at least a few comets visible from Earth through telescopes.
Are comets smaller than a grain of sand?
No. Comets are usually a few thousand feet to a few miles wide. An object smaller than a sand grain would not be visible in space.Meteors which enter the earth's atmosphere are often sand grain sized, but the once we can see are usually from pebble sized objects.
What comets would you see on a trip from Earth to Titan?
That will depend on when you make the trip. There are MANY comets detected each year, although only a few become bright enough to be seen with the naked eye, and very few are bright enough to be seen with the naked eye from bright city lights. We typically detect comets when they are about a year out from the Sun, although a flurry of smaller "Sun-diving" comets were detected only hours before they fell into the Sun in December, 2010.
The point at which Earth is closest to the sun?
That point is called the "perihelion" of Earth's orbit.We pass it during the first few days of January.
How often are comets seen?
Comets are typically visible from Earth every few years, with some being more frequently observed than others. Most comets are only visible for a short period of time as they move through the inner solar system. Astronomers actively monitor for new comets using telescopes and observatories.
What are NEAs?
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
