Lunar craters Lunar craters Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts. The word "crater" was adopted from the Greek word for vessel - (Κρατήρ a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Schroeter (1791), extending
Solar eclipses on the Moon at 43.31°S) where the temperatures remains high. Some craters are slightly cooler but as warm as the surface and warmer than areas outside the mares (basins) such as Copernicus and Langrenus. On the Moon, when there is a partial eclipse, one example is when half of the Sun is blocked (north or south), a part of the Moon has a partial eclipse (north or south). In some partial eclipses when the center of the Earth's shadow misses the Moon, one example is one hemisphere has a partial eclipse and the other does not. In some eclipses when the center of
