A comet's tail is formed when the Sun's radiation and the pressure of light drive the very thin gases and very small particles that form the head of a comet away from the head.

The tail of a comet is longest when the comet is?

The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.


Which heavenly bodies appear in the sky at regular bit long intervals and have a tail?

Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.

What direction does comet's tail go?

A comet's tail always points away from the Sun, regardless of the direction the comet is traveling. This occurs due to the solar wind and radiation pressure from the Sun, which pushes the gas and dust particles in the tail away. As a result, a comet's tail can extend for millions of kilometers and can appear bright and elongated, creating a striking visual effect in the night sky.


What is an icy rock that has bright tail when it comes close to the sun?

It is called a comet. The tail is formed out of gases and particles as it melts on its path round the Sun.

What is a bright stream of gas that is blown off a comet?

A bright stream of gas blown off a comet is called a coma. This coma is created when the sun's heat causes the ice and rocky materials within the comet to vaporize and release gases and dust into space.


What is an icy rock that has bright tail when it comes close to the sun called?

You're fishing for "comet", but the setup of your riddle is defective.-- A comet need not necessarily be in orbit around the sun.Its appearance may be a once-in-eternity event.-- A comet only has a 'tail' during the small portion of its orbitwhen it's relatively near the sun.-- The whole notion of a "tail" is misleading. That particular whatchamacallitalways points away from the sun, so when the comet has rounded the sunand is headed out again, the so-called 'tail' goes in front of it.a comet


When a comet passes near the Sun part of it takes on the appearance of a large bright ball from which the tail extends.?

Agreed.


What is the rock that has bright tail when it close to the sun?

It's called a comet. They're usually cimposed of rock and ice. As the object gets close to the sun, the heat causes the ice to evaporate, and the rock to melt. This is seen as the comet's 'tail'.
