2. Astr Astronomy cont... The stars are so far away from each other that light would need years to travel from one star to another. That is why astronomers measure distances in light years. Light Years: The distance a ray of light would travel in one year (6 trillion mi, 9.4 trillion km) https://upload.wikimedia.org/wikipedia/commons/8/82/Milky_Way_Galaxy. jpg

3. It takes 8 minutes for the light of the sun to reach Earth. This means the sun is 8 light minutes away from us. If the Sun were to disappear, how long would it take us to know that? http://www.nasa.gov/images/content/756752main_20130620-m2.9flare- orig_full.jpg

4. The Universe Universe: is all the space and matter. Galaxies, solar systems, sun, moons, planets, asteroids, meteoroids and comets are all part of our Universe. mets. Universe Galaxy Solar system Sun/star, Planets, Moons, Asteroid, Meteoroids, Comets.

5. Galaxies What is a Galaxy? A Galaxy is a group of stars, matter and gas, all held together by the force of gravity. * Example: Milky Way Galaxy *Gravity: An attractive force between objects that have mass. http://images.slideplayer.com/23/6863643/slides/slide_27.jpg

6. The Solar System Solar system - A collection of planets and their moons that orbit around ONE star. ●The Planets: According to the International Astronomical Union, an object to be a planet, it needs to be a round ball/sphere, big enough(Sorry PLUTO :) and orbits the sun.* Moon: Is an object that orbits a planet. Star: A huge object of superheated gas. *http://www.smithsonianeducation.org/educators/lesson_plans/universe/smithsonian_siyc_spring2010.pdf
