PSR 1257 12 (Pulsar) Facts

PSR 1257 12 Facts

Location of PSR 1257 12

The location of the pulsar 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 object is compared to the celestial equator and is expressed in degrees. For PSR 1257 12, the location is 13h 00m 04.00 and 12° 40` 56.00 .

Physical Properties (Age) of PSR 1257 12

PSR 1257 12 Colour and Temperature

PSR 1257 12 has a spectral type of P.

The star is believed to be about 1.00 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

Distance to PSR 1257 12

The Parallax of the star is given as 1.41 which gives a calculated distance to PSR 1257 12 of 2315.68 light years from the Earth or 709.98 parsecs. It would take a spaceship travelling at the speed of light, 2315.68 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 146,442,866.71 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.
