History of the telescope received the report in November, and the English mathematician and astronomer Thomas Harriot, who used a six-powered telescope by the summer of 1609 to observe features on the moon. The Italian polymath Galileo Galilei was in Venice in June 1609 and there heard of the "Dutch perspective glass" by means of which distant objects appeared nearer and larger. Galileo states that he solved the problem of the construction of a telescope the first night after his return to Padua from Venice and made his first telescope the next day by fitting a convex lens in one extremity of a leaden
Lunar craters named lunar craters are "satellite craters": their names consist of the name of a nearby named crater and a capital letter (for example, , , and so on). Lunar crater chains are usually named after a nearby crater. Their Latin names contain the word "Catena" ("chain"). For example, "Catena Davy" is situated near the crater Davy. The red marker on these images illustrates the location of the named crater feature on the near side of the Moon. 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
