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 the surface appears not just black but red and brown (according to the Danjon scale) because the only sunlight available is refracted through the Earth's atmosphere on the edges of the Earth forming an atmospheric ring as it is shown in the sky in a painting by Lucien Rudaux. During eclipses with long totality, temperatures plunges but not in many parts of its mares especially Oceanus Procellarum and Mare Tranquillitatis, and mid to large craters (especially with basalt floor) mostly in the middle portion of the Moon, some young craters and a few distant large craters, notably Tycho (being located
