WebQuestion Date: 2003-04-29. Answer 1: The moon orbits the earth in a nearly circular pattern every 27.3 days. The moon's orbit is tilted approximately 5 degrees off of the path of the plane of the ecliptic (or the path that the sun appears to trace across the sky), and orbits at a distance of almost 240,000 miles from the earth. Answer 2: WebNov 8, 2024 · The Moon's orbit around Earth is tilted relative to Earth's orbit around the Sun. This tilt is the reason why we have occasional eclipses instead of eclipses every …

Moon - Wikipedia

The orbit of the Moon is a nearly circular ellipse about the Earth (the semimajor and semiminor axes are 384,400 km and 383,800 km, respectively: a difference of only 0.16%). The equation of the ellipse yields an eccentricity of 0.0549 and perigee and apogee distances of 362,600 km and 405,400 km respectively (a … See more The Moon orbits Earth in the prograde direction and completes one revolution relative to the Vernal Equinox and the stars in about 27.32 days (a tropical month and sidereal month) and one revolution relative to the See more About 1000 BC, the Babylonians were the first human civilization known to have kept a consistent record of lunar observations.
