Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. In the case of a star, its the galactic centre. Megrez is a hydrogen-fusing dwarf still on the main sequence, located at around 80.5 light-years away from us. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. It is purely that the distance was recalculated.The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 2.30000 km/s with an error of about 1.20 km/s . Link by name to the catalogue in VizieR: CCDM J09036+4709AB: AG+47 796: AKARI-IRC-V1 J0903375+470923: BD+47 1633: FK5 341: HD 77327: HIC 44471: HIP 44471: HR 3594: IRAS 09002+4721: 2MASS J09033754+4709236: PLX 2162: PPM 50987: SAO 42661: TD1 13436: TYC 3424-1626-1 : uvby98 100077327: WDS J09036+4709AB: … All messages will be reviewed before being displayed. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

U.G. The figure of 441.34 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012.All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun.
If you used the 1997 Parallax value, you would get an absolute magnitude of -1.99 If you used the 2007 Parallax value, you would get an absolute magnitude of -1.63. Alkaphrah Facts.

Apparent Magnitude is also known as Visual Magnitude. As Galen Gisler said about his recent photo, ‘The two stars below the comet are at right, Iota Ursae Majoris and left, Kappa Ursae Majoris, magnitudes 3.14 and 3.56 respectively’. Because of its moderate brightness, Alkaphrah should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution. A name is preferred even if its a random made up one by yourself.The time it will take to travel to this star is dependent on how fast you are going. It is the 11 th brightest star in Ursa Major. There's no register feature and no need to give an email address if you don't need to.
A faint star will have a high number.The location of the main sequence star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth.
