Timekeeping on the Moon is an issue of synchronized human activity on the Moon and contact with such. The two main differences to timekeeping on Earth are the length of a day on the Moon, being the lunar day or lunar month, observable from Earth as the lunar phases, and the rate at which time progresses, with 24 hours on the Moon being 58.7 microseconds (0.0000587 seconds) faster, [1 ...
Shadows and detail are most pronounced along the "terminator", the dividing line between the illuminated (day side) and dark (night side) of the Moon. It is a common misconception that the moon is not visible during the daytime , although if the moon is a thin crescent or close to the Sun, viewing can require using a telescope.
The most basic moondial is accurate only on the night of the full moon. Every night after that, it loses on average [a] 48 minutes, while every night preceding the full moon it gains 48 minutes. Thus, one week to either side of the full moon, the moondial will read 5 hours and 36 minutes before or after the correct time. [citation needed]
The near side of the Moon is the lunar hemisphere that always faces towards Earth, opposite to the far side. Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth—a situation known as tidal locking. The Moon is directly illuminated by the Sun, and the cyclically ...
For almost two months, Earth will joined by a new mini-moon in it's gravitational orbit.
This may not be the last time we encounter this space rock
There's a new moon on the horizon. The Earth will gain a second, mini-moon on Sept. 29, but it won't stick around too long. Here's what to know.
Diurnal libration is the small daily libration and oscillation from 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 ...
