Earth tide reason, it is believed that many of the exoplanets are captured in higher spin-orbit resonances with their host stars. Earth tide Earth tide (also known as solid Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer. The largest body tide constituents are semi-diurnal, but there are also significant diurnal, semi-annual, and fortnightly contributions. Though the gravitational forcing causing earth tides and ocean tides is the same, the
Solar eclipses on the Moon Solar eclipses on the Moon Solar eclipses on the Moon are caused when the Earth passes in front of the Sun, blocking its light. Viewers on Earth will see a lunar eclipse. The solar eclipses are only seen in the Nearside portion and smaller parts of the Farside where the Earth is seen during librations, making up the visible portion of the Moon and eclipses there are seen during the lunar sunrise and sunset as well as furthermost areas of the Nearside but mainly not in the polar areas of the Moon. As the Moon revolves around the Earth, the
