The motion of moon around the earth is______

Answer:

revolution

Explanation:

The motion of moon around the earth is revolution.

Revolution: Completing one cycle around a focii or a center.

Answer 2

Explanation:

Not to be confused with Lunar orbit (the orbit of an object around the Moon).

The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about 27.32 days (a sidereal month) and one revolution relative to the Sun in about 29.53 days (a synodic month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4,600 km (2,900 mi) from Earth's center (about 72% of its radius). On average, the distance to the Moon is about 385,000 km (239,000 mi) from Earth's center, which corresponds to about 60 Earth radii or 1.282 light-seconds.

Period of

orbit around Earth (sidereal) 27.322 days

orbit around Earth (synodic) 29.530 days

With a mean orbital velocity of 1.022 km/s (0.635 miles/s),[9] the Moon covers a distance approximately its diameter, or about half a degree on the celestial sphere, each hour. The Moon differs from most satellites of other planets in that its orbit is close to the ecliptic plane instead of that of its primary (in this case, Earth's) equatorial plane. The Moon's orbital plane is inclined by about 5.1° with respect to the ecliptic plane, whereas the Moon's equatorial plane is tilted by only 1.5°.
