Why does a comet have a tail at the end?

Answer 1

Comets reflect light from the sun. This is the same way you see the moon glowing. When a comet's orbit nears the Sun it starts to warm up since they are usually black in colour. Water vapour sublimes from the surface of this 'dirty snowball' and forms a cloud of ice crystals known as the 'Coma'. It is this white cloud that reflects sunlight and makes it visible to us.

Answer 2

A comet's tail is formed by the solar wind pushing on the comet's coma (the cloud of gas and dust surrounding the comet's nucleus). This results in the material in the coma being stretched out into a tail that points away from the Sun. The tail always points away from the Sun due to the force of the solar wind.

Answer 3

As a comet approaches the sun a coma or tail forms from gases and dust released from the comet as it thaws in the warming sunlight. The solar wind pushes the tail away from the sun, the tail therefore is always being blown away from the sun no matter what position the comet is in with respect to the sun.

Answer 4

Comets only develop tails when approaching a star which, in the case of our solar system, means the sun. As they approach the sun, they warm up and frozen parts of the comet (for example water / ice) begin to vaporize, leaving behind the vapor trail that we see as the tail.

Answer 5

Comets have a bright tale because they are made of ice so when the ice melts it wakes a bright tail out of molten ice (water)

Answer 6

Comets are beautiful to watch in the night sky. It's tail 'glows' because of the suns radiation pressure and solar wind when the comet reaches the inner solar system.

Answer 7

The gases ejected from their surface and the reflected light from the sun make the tails glow. i suc

Answer 8

Comets have bright tails from the dust and gas. Comets are boulders in space made up of rock and ice with some gas and dust

Answer 9

A comet has a gravitational pull that attracts dust and ice from space which crates a tail behind it

Answer 10

When a comet passes by the sun, the heat from the sun evaporates the ice, frozen dust, and other materials in the comet, as a result, we see a "tail".
