Most likely you are referring to a Nebula, but there are other astronomical objects made of a cloud of dust.
A comet is a celestial body made up of ice, dust, and rocky material that orbits the sun. When a comet approaches the sun, the heat causes its ice to vaporize, creating a glowing coma (a mass of frozen gas) around the nucleus.
A frozen ball of dust and gas revolving around the sun could describe the planet Pluto. The planet, Pluto, was downgraded to a frozen ball dust and no longer considered to be a planet to scientists and astronomers.

It sounds like you are describing a nebula, which is a cloud of gas and dust in outer space. Nebulae can be illuminated by nearby stars, and their colors and shapes can vary depending on the composition of the gas and dust within them.
It is a comet.
A comet is an object that consists of a frozen mass of ice and dust. Comets have tails of gas and dust that form when they approach the Sun and their ice begins to vaporize.

A small frozen mass of dust and gas revolving around the sun. It lights up.

Wats and aliptical
A diffuse mass of interstellar dust and gas is known as a nebula. Nebulae are often regions where new stars are forming, as the dust and gas are the raw materials from which stars are born. They can vary in size, shape, and composition.
I think it's comets

No. That description most closely matches a comet.

a protostar
A small object made of frozen gas and dust is called a comet. Comets are often referred to as "dirty snowballs" and travel through space in elongated orbits around the sun. When comets come closer to the sun, the frozen gases begin to vaporize, creating a glowing coma and tail.
