SOLAR SYSTEM

Detailed explanation-1: -By exploring the conditions in the surface layers of comets as their orbit comes close enough to the sun, the ‘perihelion’ point in its orbit, the research found it can get hot enough and sustain high enough pressures to form liquid water.

Detailed explanation-2: -From the study of spectrograms, it is known that comets are made largely of compounds of carbon, oxygen, nitrogen, and hydrogen. These compounds include water, ammonia, methane, carbon monoxide, and smaller amounts of other, more complex compounds. The dust in comets is composed of silicates and some metals.

Detailed explanation-3: -Comets are huge ice and dust particles that revolve around the Sun in an orbit. Thus, comets are part of our solar system.

Detailed explanation-4: -What Is a Comet? A comet is a big ball of particles, including rocks, ice and dust. This big ball containing most of the material is called a nucleus. Comets are found traveling throughout space. When they come close to the sun, the particles in the comet heat up.
