What does it mean if something is a celestial object?

It is found in outer space 

500

Explain the difference between mass and weight.


Mass = amount of matter (stays the same).

Weight = force of gravity pulling on you (changes on different planets).

500

What is a satellite?


A satellite is an object that orbits a planet.

500

What are the 3 rules to be considered a planet ?

1. Must orbit a star

2. Must be spherical shape

3. Must have clear orbit  

500

Explain why your mass stays the same but your weight changes on different planets.

Mass doesn’t change because it’s the amount of matter in your body. Weight changes because different planets have different gravity.
