Question

Write a detailed note on comets.Answer the given question pointwise.

Answer 1

A comet is a ball of mostly ice that moves around in outer space. Cometsare often described as "dirty snowballs. The orbital inclinations of comets are usually high and not near the ecliptic where most solar system objects are found. Most of them are long-period comets and come from the Kuiper belt.

Comets are icy bodies in space that release gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.

Answer 2

Comets

• A small celestial body which is composed of ice, rock and comets dust loosely packed together, it is called comets.
• It is also called as "dirty snowball".
• A comet heats up as it approaches the Sun and builds up an atmosphere.
• The Sun's warmth makes the comet's frosts change to gases so its size or state gets bigger.
• The size of the comet may expand a huge number of kilometers.
• The weight of daylight and fast sun based particles (sunlight based breeze) can blow the residue and gas from the Sun, which leads to the formation of the tail.
• Comets have two tails―a dust tail and a particle (gas) tail.
