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 is periodicity as it relates to comets?
A comet that takes the same time to make its orbit of the Sun. We can predict with a good degree of accuracy as to when we can see it again. Halley's Comet is the most famous, coming about every 75 or 76 years. It is not totally precise as it can vary, so we can only say about every 75 or 76 years.
What is a small icy body usually with an elliptical orbit and a tail when near to the sun?
The tail is not of light itself, but consists of icy particles (mostly gas) reflecting light from the sun. Such objects are known as comets. Comets that originate from the Kuiper Belt, a ring of dirty ice balls in orbit out beyond Neptune, are short period comets. They orbit the sun once a century or so, until all the ice and gas burn off and they probably become asteroids. Comets from much further out (the Oort Cloud) generally do not orbit in the plane of the solar system, and are usually long period comets. These orbit only once every few thousand years, sometimes only once per hundred thousand years or more.
How do the tails of the comet and coma relate to loss of matter and the comet's life span?
Collisions between objects in the Kuiper Belt produce fragments that become comets. The comets are known as short-period comets. Short-period comets take less than 200 years to orbit the sun. Therefore, they return to the inner solar system quite frequently, perhaps every few decades or centuries. Short-period comets also have short life spans. Every time a comet passes the sun, it may lose a later as much as 1m thick.
Does it snow in Chico?
It only snows once in a blue moon. About once every few years.
How long is comet shoemaker levy 9's orbit period?
That's known as the comet's orbit. Each comet is different - some only taking a few years to complete an orbit, while others can take hundreds of years. The most famous 'Halley's comet' orbits once every 76 years.
Which is the only country that has been represented at every modern olympic games summer and winter?
This Will Be Found Out In A Few Years ....
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.
Why are the sighting of some comets so many years apart?
Comets have highly elliptical orbits that can take them far from the Sun for long periods of time. This means that some comets may only be visible from Earth every few decades or even centuries when they come close enough to the Sun to be seen.
What is the name of the comet that supposedly appears every 2000 years or so and was last seen in the mid 90's?
"Periodic" comets reappear at predictable intervals, such as Haley's Comet. Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.
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.
How many hyper giant stars exist in the universe?
Hypergiants are relatively rare. Only a few stars become hypergiants, and they don't last very long (only a few million years). Probably a few in every major galaxy.
