Moon the correct values of about 60 and 0.273 respectively. Archimedes (287–212 BC) designed a planetarium that could calculate the motions of the Moon and other objects in the Solar System. During the Middle Ages, before the invention of the telescope, the Moon was increasingly recognised as a sphere, though many believed that it was "perfectly smooth". In 1609, Galileo Galilei drew one of the first telescopic drawings of the Moon in his book and noted that it was not smooth but had mountains and craters. Telescopic mapping of the Moon followed: later in the 17th century, the efforts of Giovanni
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
