No. The tail of a comet is just dust and vapor blown away from the comet by the solar wind. It is visible only because it reflects the Sun's light. The closer the comet is to the Sun, the more vapor and dust will be released, and the longer the comet's tail will be.

It also depends on our viewing angle to the comet is. If the comet's tail is perpendicular to our line of sight, the comet tail will appear longer. If the comet's tail is pointed toward Earth or away from it, then the tail may appear very short or may not be visible at all.

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.


What do we see comets as?

Comets are seen as bright, icy bodies that orbit the Sun. When they get closer to the Sun, they release gas and dust in a glowing coma and often develop a tail that points away from the Sun due to solar wind.


Do comets or asteroids have a gas tail?

Comets!


What a heavenly body that has a head and a tailand orbit around the sun?

That sounds like the description of a comet. However, please note that comets ONLY have a tail when they are close to the Sun. During most of their orbit, they are too far away from the Sun to have a tail.


How are asteriods and comets alike?

Asteroids and comets are both celestial bodies that orbit the Sun. They are remnants from the formation of the solar system and are composed of rock, metals, and other materials. However, comets are distinguished by their icy composition and tail of gas and dust when they approach the Sun.

Do comets gain slightly in mass with each orbit around the sun?

Comets do not gain mass with each orbit around the sun. Their mass remains relatively constant as they travel through space. However, comets may lose mass gradually over time as they release volatile materials such as water vapor and dust, which form the comet's tail.


How do comets behave?

Comets are just very icy asteroids, they become comets when a large enough of a body of mass, i.e. jupiter or saturn. When this happens, the asteroid gets thrown into an extremely high elliptical orbit. They ideally have an orbit perpindicular to the ecliptic.


How are comets asteroids and meteorites different?

Asteroids orbit the Sun between the orbits of the planet Mars and the planet Jupiter. Comets orbit the Sun on very elliptical orbits, originating from the Kuiper belt beyond the orbit of Neptune or the Oort cloud at the edges of the solar system. Comets are also usually (but not always) icy bodies that give of gas and dust (a tail) as they approach and get heated by the Sun. Meteorites are bodies that were Asteroids or Comets that have hit the planet Earth and landed on the surface.


What is composed of ice frozen gases and rocks?

Comets are composed of ice, frozen gases, rocks, and dust. When they orbit closer to the sun, they form a glowing coma and a tail as the ice and gases vaporize.


Where do you find comets?

Comets are typically found in the outer regions of the solar system, beyond the orbit of Neptune. They can be observed from Earth when they come closer to the sun and develop a visible tail due to the solar wind. Astronomers track comets using telescopes and space missions.
