Every 18.6 years, the angle between the Moon's orbit and Earth's equator reaches a maximum of 28°36′, the sum of Earth's equatorial tilt (23°27′) and the Moon's orbital inclination (5°09′) to the ecliptic. This is called major lunar standstill. Around this time, the Moon's declination will vary from −28°36′ to +28°36′.
Dec 2, 2022 · An enduring myth about the Moon is that it doesn't rotate. While it's true that the Moon keeps the same face to us, this only happens because the Moon rotates at the same rate as its orbital motion, a special case of tidal locking called synchronous rotation. The animation shows both the orbit and the rotation of the Moon. The yellow circle ...
Nov 3, 2023 · The apex of the orbit is the optic foramen (canal), bound medially by the body of the sphenoid bone and laterally by the lesser wing of the sphenoid bone. It is medial to the superior orbital fissure. The optic foramen provides passage for the optic nerve (CN II) and ophthalmic artery to exit the skull.

Nov 5, 2016 · The Moon’s sidereal orbital period and rotational period are the same – 27.3 days. This phenomena, known as synchronous rotation, is what allows for the same hemisphere to be facing Earth all ...
Jan 11, 2024 · The orbit changes over the course of the year so the distance from the Moon to Earth roughly ranges from 357,000 km to 407,000 km, giving velocities ranging from 1.100 to 0.966 km/s. Lunar Atmosphere
The orbit and rotation period of the Moon are identical - 27.3 days. The Moon has a synchronous (or captured) rotation which means it keeps the same side or face towards the body it orbits. This means that from Earth only one side or hemisphere can be seen. The Moon has a day and night and receives sunlight on every area of its surface; an ...

May 23, 2023 · The point in the moon's orbit when it is closest to Earth is called perigee, often referred to as a "supermoon." At perigee, the moon is approximately 224,000 miles (360,000 km) from Earth.
