A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.
In revenge, the monster comes back sometimes to eat the Moon or the Sun which exit immediately, giving rise to moon and solar eclipses. [citation needed] When there is an eclipse, some Mongolians believe it to mean that Raah devours the Moon or the Sun and they make a lot of noise so that the monster liberates the eclipsed star.
In astronomy, planetary transits and occultations occur when a planet passes in front of another object, as seen by an observer.The occulted object may be a distant star, but in rare cases it may be another planet, in which case the event is called a mutual planetary occultation or mutual planetary transit, depending on the relative apparent diameters of the objects.
The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
Saturn’s Moon Mimas, known as the “Death Star”, has revealed a new secret.. A “remarkably young” ocean appears to be hiding under the icy, cratered surface of the world that led to it ...
As a planet eclipses/transits its host star it will block a portion of the light from the star. If the planet transits in-between the star and the observer the change in light can be measured to construct a light curve. Light curves are measured with a charge-coupled device. The light curve of a star can disclose several physical ...
The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction or opposition. Solar and lunar eclipses occur at times of syzygy, as do transits and occultations. The term is often applied when the Sun and Moon are in conjunction or in opposition . [4]
