This is a non-contact force that acts on objects. If two objects are placed in space, they will be drawn towards each other by this force.
What is gravity?

This planet features the highest surface temperature of all terrestrial planets, and is similar in size to the earth

What is Venus?

These missions put people on the moon and returned lunar samples to earth.

What are the Apollo missions?

This fortress orbiting the earth is where many astronauts and researchers live. It was built by the efforts combined by many countries around the world and often has space shuttles dock with it to drop off supplies and exchange crew members.
What is the International Space Station?
200
This is a HUGE system of gas, dust, and stars. Our solar system is found at one of the far edges of it.
What is the Milky Way Galaxy?

This early astronomer is mostly remembered for his laws of planetary motion, the rules which all orbiting bodies follow

Who was Kepler?
