| What's the difference between "rotation" and "revolution?" | rotation = spin, revolution = orbit |
| What's the difference between an astronomical unit (AU) and a light year (LY)? | AU – distance from sun to earth, LY – distance light travels in one year |
| How long is one of earth's rotation? What do we call that? | 24 hours, 1 day |
| How long is one of earth's orbit around the sun? What do we call that? | 365.25 days, 1 year |
| What causes seasons? | 23 degree tilt & the 365 day orbit |
| What is the geometric name for the shape of earth's orbit? | Elliptical (but remember, its essentially a circle!!) |
| If it is winter in the N. Hemisphere, what season is it in the S. Hemisphere? | Summer |
| What and when is the Summer Solstice? | June 20th – longest day |
| What and when is the Winter Solstice? | Dec 20th – shortest day |
| What and when is the Fall Equinox? | Sept 20th – equal daylight nighttime hours |
| What and when it the Spring Equinox? | March 20th – equal daylight nighttime hours |
| Are the seasons more mild or more crazy at earth's north and south poles? | Crazy |
| What does "eclipse" mean? | To cover up, to go in front of… |
| Solar eclipse literally means …. | The sun is being “eclipsed” (covered up) by the moon |
| Lunar eclipse literally means … | The moon is being “eclipsed” (covered up) by the earth |
| How big is the moon compared to the sun? | 400x |
| How far away compared to the sun? | 400x |
| Why don't we have a lunar and solar eclipse every month? | The moon’s orbit is 5% tilted off of the earth’s orbit around the sun. |
| How was the moon made? | A large asteroid hit the earth causing pieces of the asteroid and earth to be ejected. |
| Gravity? | 1/6 of earth |
| How hot during the day? | 265F |
| How cold during the night? | -310F |
| What does the phrase “far side of the moon mean?” | It’s a reference to the back half of the moon |

| What does waning mean? | To shrink |
| What does crescent mean? | Cresent shape |
| What does gibbous mean? | To stick out |
| Are all stars the same? | No |
| Do stars have a life cycle? | Yes |
| Do stars rotate around larger things or do they just stand still in space while everything else moves around them? | Stars are part of a galaxies and rotate around the black holes in the middle of the galaxies |
| Are galaxies made of universes or are universes made of galaxies? | Universes made of galaxy |
| What's at the center of most galaxies? | Super-massive black holes |
| Is the universe getting bigger, smaller, or staying the same size? | Bigger |
| Why do we think everything started with a big bang? | Since everything is moving away from everything else, if you rewind the “tape” of the universe that means at the beginning everything was right next to each other. |
| How do we know anything about anything in outer space? | Light, Electromagnetic Spectral Signature, and Red Shifts |
| What are Red Shifts? | As any object moves away from another object the visible light section of the EM spectrum receives more red wavelengths of light causing the light to be more red in color. |
| What are Electrom;agnetic Spectral Signature? | Every object in the universe has a unique pattern of the EM spectrum that it absorbs and reflects. |
