A transient lunar phenomenon (TLP) or lunar transient phenomenon (LTP) is a short-lived change in light, color or appearance on the surface of the Moon. The term was created by Patrick Moore in his co-authorship of NASA Technical Report R-277 Chronological Catalog of Reported Lunar Events , published in 1968.
Alphonsus is an ancient impact crater on the Moon that dates from the pre-Nectarian era. [1] Older sources state that it is Nectarian in age. [ 2 ] ) It is located on the lunar highlands on the eastern end of Mare Nubium , west of the Imbrian Highlands , and slightly overlaps the crater Ptolemaeus to the north.

The Moon is Earth's only natural satellite, orbiting at an average distance of 384 399 km (238,854 mi; about 30 times Earth's diameter). It faces Earth always with the same side. This is a result of Earth's gravitational pull having synchronized the Moon's rotation period with its orbital period (lunar month) of 29.5 Earth days.
TESS uses a novel highly elliptical orbit around the Earth with an apogee approximately at the distance of the Moon and a perigee of 108,000 km (67,000 mi). TESS orbits Earth twice during the time the Moon orbits once, a 2:1 resonance with the Moon. [31] The orbit is expected to remain stable for a minimum of ten years.
A subsatellite, also known as a submoon or informally a moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet. [3] It is inferred from the empirical study of natural satellites in the Solar System that subsatellites may be rare, albeit possible, elements of planetary systems. In the Solar System ...
Strange glowing lights on the Moon are recorded from Earth for centuries. This phenomenon, known as "transient lunar phenomena", is now generally accepted to be visible evidence of meteoroids impacting the lunar surface. But others with an amorphous reddish or whitish glows or even as dusky hazy regions that change shape or disappear over ...
Herschel Crater on Saturn's moon Mimas. The depth of the transient cavity is typically a quarter to a third of its diameter. Ejecta thrown out of the crater do not include material excavated from the full depth of the transient cavity; typically the depth of maximum excavation is only about a third of the total depth. As a result, about one ...
