ALL RIGHT! The sun with the group of celestial bodies that revolve around it is called a SOLAR SYSTEM! Keep moving!

All of space and everything in it is the definition of the UNIVERSE! ALL RIGHT! Keep moving!

A unit of distance equal to the distance that light travels in one year is called a LIGHT YEAR! ALL RIGHT! Keep moving!

A major body (not a comet or asteroid) orbiting around a star is also known as a PLANET! ALL RIGHT! Keep moving!

The brightness of a star if it were a standard distance from Earth is called the star’s ABSOLUTE MAGNITUDE! ALL RIGHT! Keep moving!

A large collection of stars, gas and dust held together by mutual gravitation is what scientists call a GALAXY! ALL RIGHT! Keep moving!

The brightness of a star as seen from Earth is called the star’s APPARENT MAGNITUDE! ALL RIGHT! Keep moving!

A natural, luminous, celestial body is better known as a STAR! ALL RIGHT! Keep moving!

ALL RIGHT! Keep moving!
