Encyclopedia
Lacus Aestatis consists of two relatively small areas of lunar mare
located near the western limb of the Moon
. The selenograpic coordinates of this feature are 15.0° S, 69.0° W, and it lies within a diameter of 90 km. The lake has a combined surface area in the order of 1,000 km2.
The northwestern part of this feature is located to the east-southeast of the crater Rocca
, and is contained within the rim of the satellite crater Rocca A. The other part lies to the southeast of the first, and forms an elongated, irregular patch that extends generally in a north-south direction. The southern tip lies about one crater diameter to the northwest of the flooded crater Crüger

Lunar mare
The lunar maria are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and...

Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Crüger (crater)
Crüger is a lunar crater that is located in the western part of the Moon, to the northeast of the much larger walled plain Darwin.The most distinctive feature about this crater is very dark interior floor that is one of the lowest albedo features on the Moon. The surface has been covered in...
