Yes.
A cloud of gas surrounding the nucleus.
Nucleus coma tail
1-nucleus 2-coma 3-tail
Comets are called this because of the ice and dust inside the nucleus. Now go look up everything else on your own.
particle
Dust particles
You don't need to; the Sun does a fine job of vaporizing the volatile chemicals in the nucleus of a comet.
The solid object at the head of a comet is called the comet nucleus.
coma
A nucleus first forms of rocks and frozen gases. Solar radiation or solar wind acts on this nucleus to form a comet
Comets shine due to the reflection of sunlight off their icy nucleus and dust particles surrounding it. When a comet approaches the Sun, the heat causes the nucleus to melt and release gas and dust, forming a glowing coma and tail visible from Earth.
A comet has a frozen nucleus and can develop a glowing tail when it gets close to the Sun. The heat from the Sun causes the icy nucleus of the comet to release gas and dust, which forms a glowing tail as it reflects sunlight.
