| Question | Answer |
|---|---|
| Satellite | an object, natural (like the Moon) or artificial (man-made spacecraft), that orbits a larger celestial body |
| Meteor | a small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of light. |
| Asteroid | a small rocky body orbiting the sun. Large numbers of these, ranging in size from nearly 600 miles (1,000 km) across (Ceres) to dust particles, are found (as the asteroid belt ) . |
| Comet | a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun. |
| Meteorite | a piece of space rock (from an asteroid, comet, or meteoroid) that survives its fiery passage through a planet's atmosphere and lands on the surface |
| Meteoroid | a small, rocky or metallic body (from dust grain size up to about 1 meter) traveling through outer space, often debris from asteroids or comets |
| Gravity | the fundamental force of attraction between any two objects with mass or energy |
| Telescope | Celestron NexStar SE series or Dobsonian telescopes like the Sky-Watcher Heritage 130P |
| Orbit | the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution. |
| Revolution | Revolution |
| Rotation | the action of rotating around an axis or center. |
| Axis | a reference line for measuring coordinates on a coordinate plane |
| Dwarf planet | a celestial body orbiting the Sun that's massive enough to be nearly round but hasn't cleared its orbital path of other debris |
| Tide | the alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon and sun. |
| Equinox | the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of approximately equal length (about September 22 and March 20). |
| Solstice | an astronomical event occurring twice yearly (around June 20/21 and December 21/22) when the Earth's axial tilt is at its maximum toward or away from the Sun |
| Waxing | the moon is growing larger, from a sliver after the new moon to a full moon, symbolizing increasing light, growth, and building energy for new beginnings, intentions, and projects. |
| Waning | (of the moon) have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size. |
| Crescent | a thin, curved shape resembling a sliver of the moon, thicker in the middle and tapering to points |
