Venus is very hot because it has a thick atmosphere full of gas that traps heat from the Sun, making it even hotter than Mercury, even though it's not the closest to the Sun.

Question 18

What is the Kuiper Belt?

Accepted Answer

The Kuiper Belt is a region beyond Neptune that is filled with icy bodies and dwarf planets. It's where Pluto is found, and it's kind of like the asteroid belt but much larger.

Question 19

How do we learn about planets and other objects in the solar system?

We learn about them using telescopes to observe them from Earth and by sending spacecraft to fly by or land on them. Space missions give us lots of pictures and information.

Question 20
