GALAXY CLUSTER
Groups of galaxies that are bound together by
gravity.
3
Galaxy- Large groupings of stars in space. Our
galaxy (the Milky Way) is a spiral galaxy like
this one.

The Crab Nebula in Taurus
The Great Nebula in Orion
Nebula- Huge bodies of dust and gas that are the
birthplace of stars
The Horse Head Nebula in Orion
The Ring Nebula in Lyra
5
GLOBULAR CLUSTER Groups of 20,000 to 100,000
older stars that look like a ball of stars. They
are often located in a spherical halo around
galaxies.
6
OPEN CLUSTER Groups of about a few hundred to a
few thousand stars. They may include many young
bright blue stars.
7
Solar System The sun and nine planets and other
bodies that travel around the sun.
8
Asteroid Belt Most asteroids orbit the sun in
this area between the orbit of Mars and Jupiter
The belt is 180 million km in width and contains
thousands of asteroids that are constantly in
motion, crashing into each other at high speeds
and sending clouds of dust into space. The
combined mass of all the asteroids would only be
1/1000 the mass of the earth and if all the
asteroids were combined together their diameter
would be only half the diameter of our moon.
9
Star (our sun) A large body of mostly hydrogen
and helium gas which releases light energy by
nuclear fusion.
10
Planet a large body composed of either rock
(terrestrial) or gas (gas giant) which orbits the
sun. They shine by reflecting light from the sun.
11
Moon/Satellite- a body that orbits around a
larger body, usually a planet. Planets can have
none, one, or more than one of these.
Jupiter and two of its 4 Galilean moons (Io,
Europa, Callisto, Ganymede).
12
Earths moon
Jupiters 4 Galilean moons
13
Asteroid Small rocky bodies that orbit the sun.
They range in size from a few meters across to
more than 900 km.
14
Meteoroid a rocky body smaller than an asteroid
that orbits the sun. They are really bits of dust
or rocks from space. They can get pulled in by
earths gravity into our atmosphere. Once they
enter our atmosphere If they dont burn up they
are called meteors and land on
earth they (shooting stars)
are called meteorites.
