WD 1145+017 is a white dwarf star that can be located in the constellation of Virgo. WD 1145+017 has at least 1 Extrasolar Planets believed to be in orbit around the star.
Location of WD 1145+017
The location of the star in the galaxy is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For WD 1145+017, the location is 11h 48m 33.63 and +01 d 28 ` 59.4 .
Physical Properties (Colour, Radius) of WD 1145+017
WD 1145+017 has a spectral type of DB. This means the star is a white dwarf star.
WD 1145+017 Apparent and Absolute Magnitudes
WD 1145+017 has an apparent magnitude of 17.00 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
Source of Information
The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Stellar Age, Metallicity or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
