Answer:
I'm pretty sure it's a comet!
Explanation:
A comet's nucleus is like a snowball made of ice. As the comet nears the Sun, the ice starts to melt off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. A comet's nucleus, or heart, is the solid chunk of something in the center of its fuzzy coma.
Most comets have two tails. ... Because the comet dust particles are so small, they are pushed away from the Sun into a long tail. Another tail is made of electrically charged molecules of gas (called ions). Very rarely a comet will have a third tail made of sodium, which we usually don't see with our unaided eyes.
Very sorry if this is incorrect, I hope this helps!
