No, a comet's dust tail reflects light from the sun.
A comet emits no light of its own, until close enough to be illuminated and stimulated by radiation from the sun.

No. A light year is the distance light travels in a year, and nothing can travel faster than light. Therefore, the quickest that anything could travel a light year is 1 year. A comet travels much slower than light.
4.5 light hours
Halley's comet appears blue due to the emissions of vaporized gases, such as carbon, nitrogen, and oxygen, as it interacts with ultraviolet light from the sun. The ionization and excitation of these gases cause them to emit bluish-green light, giving the comet its characteristic blue glow.
Light from a comet is just reflected sunlight.
they don't produce their own light, it all comes from the sun, so the closer to the sun the brighter
the color of a comet is light blue or dark blue
A comet emits no light of its own, until close enough to be illuminated and stimulated by radiation from the sun.
The sun makes a comet appear bright. A comet is usually made up of ice and rock. The ice reflects the light of the sun very well.
The Coma is the nebulous envelope around the nucleus of a comet. It is formed when the comet passes close to the Sun.
Halley's Comet actually comes around every year. Humans enjoy loooking at the beautiful light show. The reason why Halley's Comet is so famous is that light show was the first comet seen that was reecorded.
The tail of a comet is luminous because it scatters and reflects the light from the sun.
The halo of light around a comet is called the coma. It is made up of gas and dust that are released from the comet as it approaches the sun and is illuminated by sunlight, creating a glowing cloud around the comet.
The comet is moving quickly across the sky.
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.
