WebMercury 's 88-day orbit around the Sun will carry it to its closest point to the Sun – its perihelion – at a distance of 0.31 AU from the Sun. Unlike most of the planets, which follow almost exactly circular orbits around the Sun only varying in their distance from the Sun by a few percent, Mercury has a significantly elliptical orbit. WebIts closest approach takes it to a distance of only 124 AU or about 17 light-hours from the black hole. This orbit, when combined with observations of other stars close to the galactic center, indicates that a mass of 4.6 million M Sun must be concentrated inside the orbit—that is, within 17 light-hours of the center of the Galaxy. literacy rates in thailand

The earliest known recorded observations of Mercury are from the MUL.APIN tablets. These observations were most likely made by an Assyrian astronomer around the 14th century BC. The cuneiform name used to designate Mercury on the MUL.APIN tablets is transcribed as UDU.IDIM.GU\U4.UD ("the jumping planet"). Babylonian records of Mercury date back to the 1st millennium BC. The WebTwo planets – Venus and Mercury – have orbits that lie inside Earth’s orbit of the Sun. When one of these planets passes between the Earth and the Sun it is called an inferior conjunction. When this alignment of Earth, and either Mercury or Venus is nearly perfect, we can observe Mercury or Venus as they move across the face of the Sun.
