The matter surrounding a comet’s core is vaporized and forms a very bright halo of gases and an enormous cloud of hydrogen envelopes the head of the comet.
A comet is a tiny, icy body in space that may be identified by its stunning tail when viewed from Earth. Only when a comet is getting close to sun, the ice and particles that make up the comet's core heat up and start to dissolve.
Therefore,the material encircling the centre vaporises and creates a very bright halo of gases and a sizable cloud of hydrogen. Most comets follow a solar orbit. The atmosphere of gas created by the ice melting is what causes the coma.
