PSR B1919+21

PSR B1919+21 Facts

Location of PSR B1919+21

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 B1919+21, the location is 19h 21m 44.815 and +21° 53` 2.25 .

Physical Properties (Radius) of PSR B1919+21

PSR B1919+21 Colour and Temperature

PSR B1919+21 has a spectral type of P. PSR B1919+21 lies at a distance of 1,000.00 light years away from our Sun and our planet Earth or to put it another way, 306.59 parsecs away from the Sun.

PSR B1919+21 Radius

PSR B1919+21 has been calculated as 1.40 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 974,120.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

Distance to PSR B1919+21

PSR B1919+21 is an estimated 1,000.00 light years from our Solar System (Earth and Sun). It would take a spaceship 1,000.00 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.
