How does the composition of a comet compare with that of the Sun?.
alekssr [168]

Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice. Sun is a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions. Comets can be compared to the sun on the basis of size, composition, and position in the solar system.

<h3>What is the sun?</h3>

The Sun is the central star of our Solar System. It's a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions.

Sun emits energy mostly as visible light, ultraviolet light, and infrared radiation. It is the most vital source of energy for life on Earth.

<h3>What are comets?</h3>

A comet is a tiny entity circling the Sun that contains a significant amount of volatile ices, which includes entrained dust particles.

The comet forms two tails, one of ionized molecules and radicals and the other of dust, as dust and gas in the coma flow freely into space.

Comets are frozen remnants of the solar system's origin, made of dust, rock, and ice.

They range in size from a few miles to tens of miles across, but as they get closer to the Sun, they heat up and spew gases and dust into a flaming head the size of a jet.

Hence comets can be compared to the sun on the basis of size, composition, and position in the solar system.

To know more about the comets refer to the link;
