Frequently Asked Questions
What is the difference between a star and a planet?
Stars have their own light and heat (like the Sun), whereas planets do not have their own light and merely reflect the light of the star they orbit.
Why do we only see one side of the Moon from Earth?
The Moon takes the exact same amount of time to complete one rotation on its axis as it does to complete one revolution around the Earth.
What is a light-year?
A light-year is a unit of astronomical distance, representing the total distance that a beam of light travels through a vacuum in one Earth year.
