it is a comet that comes super close to the sun. Or that collides with it and disinagrates.
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.
The sun creates a tail on a comet because of solar radiation and solar wind on the nucleus of the comet. A comet is an icy body that is seen when it passes close to the sun.
The comet enters the sun's orbit with a constant velocity.
Comet ISON disintegrated after passing too close to the sun.
Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.

the Sun's heat and radiation produce a wind called the Solar Wind, as a comet gets close to the Sun it begins to melt. ... This is when a comet begins to shine.
A comet's tail is always pointed away from the Sun due to the solar wind. As the comet moves closer to the Sun, solar radiation and solar wind push the dust and gas away from the comet, creating the tail that appears to extend ahead of the comet in its orbit.
