Scientific notation is used in science because - it makes it easy to write big or small numbers. The average distance from Earth to the sun is - 1 AU The sun is - a star 1 AU from Earth. more than 100 times the diameter of Earth. A galaxy contains - gas, dust, and stars, and a lot of dark matter. The Milky Way Galaxy - contains about 100 billion stars. 2.9×107 is the same as - . 29 million It takes light 1.3 seconds to travel from the moon to Earth and 8 minutes to travel from the s...

How do we classify galaxies? - We classify galaxies based on if they are spiral, elipitical or irregular. The size is determined be the halo. What kind of stars do elliptical galaxies contain? - Ellipitcal galaxies have only older stars. There is no gas or dust to create new stars. What kind of stars do spiral galaxies contain? - Spiral Galaxies contain old and new stars and much gas and dust. How is the light from active galaxies different from light from normal galaxies? - Active ga...
