Information on VFTS 102

The star is also know as 2MASS J05373924-6909510. This star has been identified as being the fastest rotating star so far discovered. The bright young star is rotating at a million miles per second or 100 times faster than our own star, the Sun. The stars speed has caused it to flat out and have a disc like appearance. The star might have had a companion, one that would not exist now. N.A.S.A

Location of VFTS 102

The location of the 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. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For VFTS 102, the location is 05h 37m 39.248 and -69° 09` 51.04 .

Physical Properties (Colour, Temperature) of VFTS 102

VFTS 102 has a spectral type of O9:Vnnne+ C. This means the star is a blue main sequence dwarf star. The star has a B-V Colour Index of 0.293 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 7,254 Kelvin.

Distance to VFTS 102

The Parallax of the star is given as 0.02 which gives a calculated distance to VFTS 102 of 163081.67 light years from the Earth or 50000 parsecs. It would take a spaceship travelling at the speed of light, 163081.67 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 10,313,168,449.20 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
