Question

Answer

This is a gk question that's why it is having no explanation but still I am trying Correct answer is option B yes A comet is a dirty snow ball orbiting around the sun. as comet is form from a useless star

Answer

Explanation:
A comet is a dirty snowball orbiting the Sun. Here's a detailed explanation:
Definition:
- A comet is a celestial object composed of ice, dust, and rocky particles.
- It is often described as a 'dirty snowball' because it consists of a mixture of water ice, frozen gases, and other organic compounds.
Composition:
- Comets are made up of a nucleus, coma, and tail.
- The nucleus is the solid core of the comet, composed mainly of ice and rock.
- The coma is the fuzzy cloud surrounding the nucleus, formed when the comet approaches the Sun and the ice starts to vaporize.
- The tail is formed as the vaporized gases and dust particles are swept away from the Sun by the solar wind, creating a glowing trail.
Orbit:
- Comets have elongated, elliptical orbits that take them far away from the Sun and then back again.
- When a comet is far from the Sun, it remains dormant, but as it gets closer, the heat causes the ices to vaporize and form a coma and tail.
- Comets can take anywhere from a few years to thousands of years to complete their orbits.
Famous Comets:
- Some famous comets include Halley's Comet, which appears every 76 years, and Comet Hale-Bopp, which was visible from Earth in 1997.
Conclusion:
In conclusion, a comet is a dirty snowball orbiting the Sun. It is composed of ice, dust, and rocky particles and has a distinct nucleus, coma, and tail. Comets have elongated orbits and can be seen from Earth as they approach the Sun and the vaporized gases create a glowing trail.

Answer

What is a Comet?
A comet is often described as a 'dirty snowball' because of its unique composition and behavior in space. Here’s a detailed explanation of why option 'B' is correct:
Composition
- Comets are made up of ice, dust, and rocky materials.
- The icy components include water, carbon dioxide, ammonia, and other gases.
- When a comet gets close to the Sun, the heat causes the ice to vaporize, creating a glowing coma and often a tail.
Orbit
- Comets follow elliptical orbits around the Sun, which can take them far out into the solar system and then bring them close to the Sun.
- These orbits can take years, decades, or even centuries to complete.
Appearance
- As a comet approaches the Sun, the heat creates a bright tail that can stretch for millions of kilometers.
- The tail always points away from the Sun due to solar winds, making comets visible from Earth.
Difference from Other Celestial Bodies
- Unlike planets or stars, comets are not massive bodies; they are relatively small and can vary in size from a few hundred meters to tens of kilometers across.
- They are not groups of stars or planets; they are unique, icy bodies that travel through space.
In summary, a comet is aptly described as a 'dirty snowball' orbiting the Sun, highlighting its icy composition and behavior as it travels through the solar system.
