Space Objects
Irregularly shaped pieces of rock, metal and dust
Asteroid
The brightness of a star
Magnitude
A small to medium sized star like our sun
Dwarf Star
Stars that regularly or repeatedly change in magnitude.
Variable stars
The scientific study of stars
The smallest star group that contains only two stars
Binary System
How bright a star appears to us
Apparent magnitude
A star that is ten to hundreds of times larger than the sun
Giant
Our galaxy, the Milky Way, is part of a cluster of more than 30 galaxies that make up what?
The Local Group
Telescopes that bend light to make objects seem larger
Refracting Telescopes
Small group of stars that contains only three or four stars held together by gravity
Multiple Star Group
The true brightness of a star or how bright a star actually is
Absolute magnitude
The largest and brightest stars, which are hundreds of times larger and thousands of times brighter than our sun
Supergiant
Two pair of stars seen together that change apparent magnitude when one star eclipses the other.
Eclipsing variable stars
Formed by the collapse of a supergiant that has a gravitational force so strong that not even light can escape.
Black hole
Comet
The color of the hottest stars
A large group of stars held together by gravity
Star cluster

Explain the differences between a Meteoroid, meteor, and a meteorite
Meteoroid - rocky object in space
Meteor - A meteoroid that moves through Earth's atmosphere which causes it to light up
Meteorite - A meteor that hits Earth's surface
A glowing ball of gas that produces light
Star
The method of a star's apparent movement over time, determining the distance from earth to a star based on the star when viewed from different angles.
Parallax
The death of a star that causes to blow apart, which appears as an increase in size and brightness
Super nova
A cloud of interstellar gases and debris
Nebula
