1 ORGANIZE YOUR SPACE! (in order from larger to smaller)

2 GALAXY CLUSTER Groups of galaxies that are bound together by gravity.

3 Spiral Galaxy in Ursa Major Galaxy- Large groupings of stars in space. Our galaxy (the Milky Way) is a spiral galaxy like this one.

4 The Horse Head Nebula in Orion The Crab Nebula in TaurusThe Great Nebula in Orion The Ring Nebula in Lyra Nebula- Huge bodies of dust and gas that are the birthplace of stars

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 Jupiter’s 4 Galilean moons Earth’s moon

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 earth’s gravity into our atmosphere. Once they enter our atmosphere If they don’t burn up they are called meteors and land on earth they (“shooting stars”) are called meteorites.
