|---|---|
| Satellite | A satellite or an artificial satellite [a] is an object, typically a spacecraft, placed into orbit around a celestial body |
| Meteor | A meteor, also known as a shooting star , is a glowing streak of a small body (usually meteoroid) going through Earth's atmosphere |
| Asteroid | An asteroid is a minor planet—an object larger than a meteoroid (thus 1 meter or larger) that is neither a planet nor an identified comet |
| Comet | A comet is an icy, small Solar System body or interstellar object that warms and begins to release gases when passing close to the Sun |
| Meteorite | A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. |
| Meteoroid | is a small body in outer space. Meteoroids are distinguished as objects significantly smaller than asteroids, ranging |
| Gravity | the fundamental force of attraction between any two objects with mass or energy |
| Telescope | an instrument that gathers and focuses electromagnetic radiation (like light) from distant objects, making them appear closer and brighter by collecting more photons |
| Orbit | orbit is the curved trajectory of an object under the influence of an attracting force. Known as an orbital revolution |
| Revolution | Orbital revolution is the movement of a planet around a star, or a moon around a planet. For example, the Earth revolves around the Sun, and the Moon revolves about the Earth |
| Rotation | Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space |
| Axis | an imaginary line through the North and South Poles, tilted at about 23.5 degrees relative to its orbit around the Sun |
| /Dwarf planet | nine largest candidates are dwarf planets – in rough order of decreasing diameter, Pluto, Eris, Haumea |
| Tide | are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) |
| Equinox | A solar equinox is a moment in time when the Sun appears directly above the equator, rather than to its north or south |
| Solstice | is the time when the Sun reaches its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. |
| Waxing | a waxing moon sets during the evening and so reduces the prospect of extra light pollution spoiling the event. |

| Crescent | It is used as the astrological symbol for the Moon, and hence as the alchemical symbol for silver. It was also the emblem of Diana/Artemis, and hence |
| Gibbous | GIBBOUS definition: (of a heavenly body) convex at both edges, as the moon when more than half full. See examples of gibbous used in a sentence |
| High tide | the tide at its highest level of elevation. the time of high water. a culminating point. the high tide of the revolution. high tide |
| Low tide | the time of low water. · the lowest point of decline of anything. |
| Flood tide | the inflow of the tide; rising tide. flood tide Scientific. The period between low tide and high tide, during which water flows toward the shore |
| Ebb tide | The period between high tide and low tide during which water flows away from the shore. · Also called falling tide |
| Tidal range | is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces |
| Spring tide | Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and are also caused by the Earth |
| Neap tide | Range variation: springs and neaps |
