¿Qué son los cometas?

Comets are icy bodies formed from particles clumped together after the formation of gas giant planets. They orbit the Sun, with long-period comets taking over 200 years and short-period comets taking less than 200 years. Comets have a nucleus and develop tails as they approach the Sun, due to evaporation. Over time, comets lose material and eventually disintegrate.

What are comets primarily made of?

• Metallic rocks

• Icy rocks

• Molten lava

Where do most long-period comets originate from?

• The asteroid belt

• The inner solar system

• A distant cloud surrounding the solar system

• The Quiter Belt

Which comet is known to return to the inner solar system every 76 years?

• Comet Swift-Tuttle

• Comet Encke

• Halley's Comet

• Comet Hale-Bopp

What is the center of a comet called?

• Nucleus

• Mantle

• Core

• Crust

What causes the ionized gas tail of a comet to always point away from the Sun?
