Question 10

How do we explore the solar system?

Accepted Answer

We explore the solar system with telescopes, satellites, and space probes. They help us learn more about planets and other space objects.

Question 11

What are comets?

Accepted Answer

Comets are icy bodies in space that have long tails when they get close to the sun. They are like dirty snowballs made of dust, rock, and ice.

Question 12

It takes the Earth one year, or about 365 days, to orbit the sun once. This is why we have different seasons as the Earth moves around the sun.

Question 15

Why do we only see one side of the moon?

Accepted Answer

We only see one side of the moon because it takes the same time to rotate on its axis as it does to orbit Earth. This is why the same side is always facing us.

Which planet is known as the Red Planet?

Accepted Answer

Mars is known as the Red Planet because of its reddish appearance. The color comes from iron oxide, or rust, on its surface.
