Photograph of the far side of the Moon, with Mare Orientale (center left) and the mare of the crater Apollo (top left) being visible, taken by Orion spacecraft during the Artemis 1 mission. The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's ...
The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
The lunar south pole at the center of this image, situated on the rim of Shackleton Crater.Mosaic image created by LROC (Lunar Reconnaissance Orbiter) and ShadowCam A view of the south pole of the Moon showing where reflectance and temperature data indicate the possible presence of surface water ice
The combination of a super moon and blue moon is rare. The full moon’s peak took place on Monday afternoon, at 2:26 p.m. EDT, but it’ll be visible until early Wednesday morning.
The magnification of the virtual image formed by the plane mirror is 1. Top: The formation of a virtual image using a diverging lens. Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f is the focal point, O is the object, and I is the virtual image, shown in grey. Solid blue lines indicate (real) light rays and ...
Across the Moon, the lunar terminator is visible, the borderline between the Moon's day and night; the lunar limb is the Moon's profile against the dark sky, top right in this picture. The lunar limb is the edge of the visible surface (disc) of the Moon as viewed from Earth. [1]
Diurnal libration is the small daily libration, an oscillation due to Earth's rotation, which carries an observer first to one side and then to the other side of the straight line joining Earth's and the Moon's centers, allowing the observer to look first around one side of the Moon and then around the other—since the observer is on Earth's ...
The night side of the moon, illuminated by earthshine, becomes visible next to the narrow crescent (11 percent, age of the moon = 3.3 days) with ash-grey moonlight. Image taken 20° over the western evening sky shortly after the equinox in spring with a particularly steep ecliptic as seen from Berlin.
