an object, natural (like the Moon) or artificial (man-made spacecraft), that orbits a larger celestial body

a meteoroid that has entered the earth's atmosphere.

any of millions of small celestial objects revolving around the sun, often irregularly shaped and having a great range in size

a celestial body moving about the sun, usually in a highly eccentric orbit, consisting of a central mass surrounded by an envelope of dust and gas that may form a tail that streams away from the sun.

a mass of stone or metal that has reached the earth from outer space; a fallen meteoroid.

any of the small bodies, often remnants of comets, traveling through space: when such a body enters the earth's atmosphere it is heated to luminosity

the force of attraction that moves or tends to move bodies towards the centre of a celestial body, such as the earth or moon

to move or travel around in an orbital or elliptical path. The earth orbits the sun once every 365.25 days.

The motion of an object around an internal axis

turning round or rotating, as on an axis

the line about which a rotating body, such as the earth, turns

a spherical celestial body revolving about the sun, similar to a planet but not large enough to gravitationally clear its orbital region of most or all other celestial bodies

the periodic rise and fall of the waters of the ocean and its inlets, produced by the attraction of the moon and sun, and occurring

the time when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth and occurring

either of the two times a year when the sun is at its greatest distance from the celestial equator:

the act or process of applying wax, as in polishing or filling.

decreasing in the extent of its illuminated portion after the full moon.

the figure of the moon in its first or last quarter, resembling a segment of a ring tapering to points at the ends.

of the moon or a planet) more than half but less than fully illuminated

the tide when it is at its lowest level or the time at which it reaches this

The period between low tide and high tide, during which water flows toward the shore.

the vertical difference between high tide and low tide

any great flood or swelling rush. a spring tide of compliments

either of the two tides that occur at the first or last quarter of the moon when the tide-generating forces of the sun and moon oppose each other and produce the smallest rise and fall in tidal level
