Earth's orbital speed averages about 30 km/s (67,000 mph), which is fast enough to cover the planet's diameter in seven minutes and the distance to the Moon in four hours.

The Hill sphere (gravitational sphere of influence) of the Earth is about 1.5 Gm (or 1,500,000 kilometers) in radius. This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun, Moon and planets.

Because of the axial tilt of the Earth in its orbit, the maximum intensity of sun rays hits the earth 23.4 degrees north of equator at the June Solstice (at the Tropic of Cancer), and the maximum intensity of sun rays hits the earth 23.4 degrees south of equator at the December Solstice (at the Tropic of Capricorn).

The Moon orbits Earth in the prograde direction and completes one revolution in approximately 27.322 days (a sidereal month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4600 km from Earth's center (about three quarters of the radius of Earth). On average, the Moon is at a distance of about 385000 km from Earth's center, which corresponds to about 60 Earth radii. With a mean orbital velocity of 1.023 km/s, the Moon moves relative to the stars each hour by an amount roughly equal to its angular diameter, or by about 0.5°. The Moon differs from most satellites of other planets in that its orbit is close to the plane of the ecliptic, and not to Earth's equatorial plane.

The moon orbits the earth in a little under 28 earth days. It travels at almost 2,290 miles per hour. Coincidentally, the moon's rotation period is also a little under 28 days, meaning the same face points toward the earth during its entire orbit. The English word month is derived from moonth, which was how long the moon was observed to take to return to a specific phase.

1 The Moon's orbital period in a non-rotating frame of reference is 27.32 days (27 days, 7 hours, 43 minutes, 11.6 seconds). 2  This is known as a sidereal month and is measured by observing how long it takes the Moon to pass a fixed star on the celestial sphere.

Earth lies at an average distance of 149.60 million kilometers (92.957 million miles) from the Sun and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles). Earth's orbit has an eccentricity of 0.0167.

1 An anomalistic month is the Moon's orbital period measured from perigee to perigee-the point in the Moon's orbit when it is closest to Earth. 2  An anomalistic month is about 27.55 days on average.

1 This is known as a sidereal month and is measured by observing how long it takes the Moon to pass a fixed star on the celestial sphere. 2  A synodic month is 29.53 days (29 days, 12 hours, 44 minutes, 2.8 seconds) and is measured from New Moon to New Moon.

Because the orbital velocity of the Moon around Earth (1 km/s) is small compared to the orbital velocity of Earth about the Sun (30 km/s), this never happens. There are no rearward loops in the Moon's solar orbit.
