Front

What is a comet?

Back

A comet is a small celestial body that orbits the sun, composed of ice, dust, and rocky material. It is often described as a 'dirty snowball' and has a nucleus, coma, and a tail that forms when it approaches the sun.

Front

What is the difference between an asteroid and a meteoroid?

Back

An asteroid is a larger rocky body that orbits the sun, primarily found in the asteroid belt between Mars and Jupiter. A meteoroid is significantly smaller than an asteroid and can be a fragment of an asteroid or a comet.

Front

What is the surface of the moon like?

Back

The surface of the moon is rough, characterized by craters, mountains, and valleys.

Front

Where are asteroids primarily found in the solar system?

Back

Asteroids are primarily found in the asteroid belt, which is located between the orbits of Mars and Jupiter.

Front

What direction does a comet's tail face when it is near the sun?

Back

The tail of a comet usually faces away from the sun due to the solar wind and radiation pressure.

Front

What is the main component of a comet's nucleus?

Back

The nucleus of a comet is primarily composed of ice, dust, and rocky material.

Front

What is the difference between a comet and a star?

Back

A comet is a small icy body that orbits the sun and develops a tail when near the sun, while a star is a massive celestial body that generates energy through nuclear fusion.

Front

What happens to a comet as it approaches the sun?

Back

As a comet approaches the sun, the heat causes the ice to vaporize, creating a glowing coma and a tail that points away from the sun.

Front

What are meteors?

Back

Meteors are the streaks of light produced when meteoroids enter the Earth's atmosphere and burn up due to friction.

Front

What is the largest asteroid in the asteroid belt?

Back

The largest asteroid in the asteroid belt is Ceres, which is also classified as a dwarf planet.
