The incredibly high level of astronomical knowledge in ancient times raises the question of why the inhabitants of ancient times needed such precise knowledge. Ancient observatories become a tool for the finest and longest lasting astronomical observations. In ancient Babylon eclipses of the Sun and the location of the planets relative to each other could be accurately calculated. In Sumer the Moon''s orbit time was known with an accuracy of 0.4 seconds. According to their calculations the duration of the year was 365 days 6 hours and 11 minutes which differs from today''s data by only 3 minutes. Sumerian astronomers knew about Pluto the most distant planet in the solar system which is open (not the first time) to modern scientists only in 1930. According to today''s data Pluto''s solar circulation time around the Sun is 90727 Earth days; the Sumerian sources include the number 90720. Mayan astronomers have calculated the duration of the lunar month with an accuracy of 0.0004 days (34 seconds). The time of Earth circulation around the Sun was equal to 365242129 days. With the help of the most precise modern astronomical instruments this number was specified: 365242198 days.
