Most comets travel around the Sun in elliptical paths. The time it takes a comet to make a complete orbit is called its period. Some comets have short periods of less than seven years. Others travel in such huge orbits that they pass near the Sun only once in thousands or even millions of years. As of 1995, 878 comets have been catalogued and their orbits at least roughly calculated. Of these 184 are periodic comets (orbital periods less than 200 years); some of the remainder are no doubt periodic as well, but their orbits have not been determined with sufficient accuracy to tell for sure. No comets seem to have approached the Sun from beyond the limits of the solar system. Therefore, all comets seen by astronomers are considered part of the solar system.
What else can I help you with?
What body forms a tail as it approaches the sun?
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
What are particles around the comet?
Particles around a comet usually include dust and gas that are released as the comet approaches the sun. These particles form a glowing cloud called a coma which envelops the nucleus of the comet. As the comet gets closer to the sun, the solar wind pushes on the particles in the coma, creating the tail that points away from the sun.
What is the path of comet around the sun called?
It is called an orbit. A comet has an eccentric or parabolic orbit.
What forces keep the comet in orbit around the sun?
The comet is kept in orbit around the sun by the gravitational pull between the comet and the sun. This gravitational force acts as a centripetal force, keeping the comet moving in its elliptical orbit.
Why is a comet visible for only a short portion of its orbit around the sun?
A comet is visible for only a short portion of its orbit around the sun because it only becomes bright and visible when it gets closer to the sun. As it approaches the sun, the sun's heat vaporizes the comet's icy surface, creating a glowing coma and tail that make it visible from Earth. Once the comet moves away from the sun, it becomes dimmer and harder to see.
Does a comet have to have two sun's to go around for it to orbit?
Considering that comets are pretty common objects in the solar system and that we have one sun only, it's obvious that a comet needs just one sun, or star, to go around.
What do comet orbit?
The Sun
What body forms a tail as it approaches the sun?
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
When did Halley's comet most recently pass around the sun?
Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.
What is the shape of a comet's orbit around the sun?
oval
What path around the Sun does the comet follow?
An orbit

What does the halleys comet revolve around?
Around the earth and past the sun.
What are particles around the comet?
Particles around a comet usually include dust and gas that are released as the comet approaches the sun. These particles form a glowing cloud called a coma which envelops the nucleus of the comet. As the comet gets closer to the sun, the solar wind pushes on the particles in the coma, creating the tail that points away from the sun.
What does hale-bopp orbit around?
Comet Hale-Bopp orbits the Sun. It is a very long-period comet; we expect it back in about 2200 years. Perhaps before then we'll go out and get it.
What is path of a comet around the sun CALLED?
An orbit
