A comet is a celestial object of ice or dust that develops one or more long tails when near the sun. Comets can appear in various colors, including red. After a comet leaves the sky, it may not return within a person's lifetime.[1]
History
Azor Ahai is prophesied to be reborn when "the red star bleeds".[2] The prince that was promised is prophesied to be born beneath a "bleeding star".[3]
Rhaegar Targaryen believed that the "bleeding star" of the prophecy was a comet. A comet was seen above King's Landing on the night Rhaegar's son Prince Aegon was conceived, which led Rhaegar to believe that Aegon was the prince that was promised.[3]

Quotes
Dany looked and saw it, low in the east. The first star was a comet, burning red. Bloodred; fire red; the dragon's tail. She could not have asked for a stronger sign.[5]
—thoughts of Daenerys Targaryen
The comet's tail spread across the dawn, a red slash that bled above the crags of Dragonstone like a wound in the pink and purple sky.[1]
—thoughts of Cressen
The maester did not believe in omens. And yet... old as he was, Cressen had never seen a comet half so bright, nor yet that color, that terrible color, the color of blood and flame and sunsets.[1]
—thoughts of Cressen
The thing in the sky is a comet, sweet child. A star with a tail, lost in the heavens. It will be gone soon enough, never to be seen again in our lifetimes. Watch and see.[1]
—Cressen, to Shireen Baratheon
He shared my belief when he was young, but later he became persuaded that it was his own son who fulfilled the prophecy, for a comet had been seen above King's Landing on the night Aegon was conceived, and Rhaegar was certain the bleeding star had to be a comet.[3]
—Aemon, to Samwell Tarly
