Facts
Sualocin is a Main Sequence Star type star. Sualocin is a B9V main sequence star based on the spectral type that was recorded in the Hipparcos star catalogue.
Location
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. 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.
Radial Velocity and Proper Motion
All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now.
Physical Properties
Based on the star's spectral type of B9V , Sualocin's colour and type is blue main sequence star. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between 10,000 and 25,000K based on the notes from Harvard University.
Apparent (Brightness) and Absolute Magnitudes
Sualocin has an apparent magnitude of 3.77, this is a measure of the brightness of the star as seen from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.57 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.69.
Travel Time
The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).
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.
How far away is the star Delphini?
