Question

Quizplus · Accepted Answer

The coma is the brightest part of a comet. This is because the coma is made up of gas and dust that are released from the nucleus as it heats up, and they reflect sunlight, creating a glowing atmosphere around the nucleus. The nucleus and tails (ion tail and dust tail) are typically much fainter in comparison.
