The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth 's surface. As Earth orbits the Sun over the course of a year, the Sun appears to move with respect to the fixed stars on the celestial sphere, along a circular path called the ecliptic . Earth's rotation about its axis causes ...
The Miracle of the Sun ( Portuguese: Milagre do Sol ), also known as the Miracle of Fátima, is a series of events reported to have occurred miraculously on 13 October 1917, attended by a large crowd who had gathered in Fátima, Portugal in response to a prophecy made by three shepherd children, Lúcia Santos and Francisco and Jacinta Marto.
Why is the Sun's corona so much hotter than the Sun's surface? (more unsolved problems in astronomy) The temperature of the photosphere is approximately 6,000 K, whereas the temperature of the corona reaches 1,000,000–2,000,000 K. The high temperature of the corona shows that it is heated by something other than direct heat conduction from the photosphere. It is thought that the energy ...
The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun. [1] [2] [a] From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. [3] The ecliptic is an important reference plane and is the basis of ...

Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares ', i.e ...
