Question 1

What is a comet?

Accepted Answer

A comet is a big ball of ice, rock, and dust that travels around the Sun. It has a glowing tail when it gets close to the Sun because the Sun heats it up.

Question 2

Where do comets come from?

Accepted Answer

Comets come from far, far away in deep space or the edge of our solar system. Some come from a place called the Kuiper Belt, while others come from the Oort Cloud.

Question 3

Why do comets have tails?

Accepted Answer

When comets go near the Sun, the heat turns part of them into gas and dust, creating a bright tail. This tail always points away from the Sun.

Question 4

How big are comets?

Accepted Answer

Comets can be really big or small. Some comets can be as small as a few football fields, while others can be bigger than a city.

Question 5

How fast do comets travel?

Accepted Answer

Comets zoom through space really fast! They can travel over 100,000 miles per hour when they're near the Sun.

Question 6

Why are comets important to study?

Accepted Answer

Comets are like time capsules because they are made of really old materials from when the solar system was formed. By studying them, scientists learn more about the early solar system.

Question 7

What is a comet made of?

Accepted Answer

A comet is mostly made of ice, dust, and little rocks. They sometimes have frozen gases inside them too.

Question 8

What happens when a comet gets close to the Earth?

Accepted Answer

When a comet passes close to Earth, we might see it in the sky as a bright object with a long tail. It’s a beautiful sight and a safe distance away.

Question 9

Can comets hit planets?

Accepted Answer

Yes, sometimes comets can crash into planets, but that doesn't happen very often. When they do, they can create big craters.

Question 10

Do all comets look the same?

Accepted Answer

No, comets don't all look the same. Some have really long tails and others have short ones. Their colors and brightness can differ too.

Question 11

How do comets get their names?

Accepted Answer

Comets often get named after the people who discover them. For example, Halley's Comet is named after the astronomer who studied it.

Question 12

What is the most famous comet?

Accepted Answer

The most famous comet is probably Halley's Comet. It appears in the sky about every 76 years, and people have been watching it for centuries.

Question 13

Why do comets have two tails?

Accepted Answer

Comets often have two tails because the Sun’s heat makes gas and dust escape. One tail is made of gas, and the other is from dust.

Question 14

What happens to comets over time?

Accepted Answer

Over time, comets can lose their ice and dust as they warm up, so they get smaller. Sometimes, they can even break apart completely.

Question 15

Are comets and asteroids the same?

Accepted Answer

No, comets and asteroids are different. Comets are icy and get tails near the Sun, while asteroids are rocky and don't have tails.

Question 16

How long does it take for a comet to orbit the Sun?

Accepted Answer

It depends on the comet. Some comets take a few years, while others take hundreds or even thousands of years to go around the Sun.

Question 17

What is the nucleus of a comet?

Accepted Answer

The nucleus is the solid center part of a comet, made mostly of ice and rock. It’s like the heart of the comet.

Question 18

How do scientists study comets?

Accepted Answer

Scientists use telescopes to watch comets from Earth, and sometimes they send space probes to visit them. This helps them learn more about what comets are made of.

Question 19

Can we predict when a comet will come back?

Accepted Answer

Yes, scientists can predict when some comets will return by studying their paths. Comets like Halley's have regular orbits that we can track.

Question 20

Why do comets have bright heads?

Accepted Answer

Comets have bright heads, called comas, because when they get warmed by the Sun, the ice turns to gas, creating a glowing cloud around the nucleus.
