PSR B1620-26

Primary Facts on PSR B1620-26

Location of PSR B1620-26

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 B1620-26, the location is 16h 23m 38.00 and -26° 31` 53.00 .

Physical Properties of PSR B1620-26

PSR B1620-26 has a spectral type of P.

PSR B1620-26 Apparent and Absolute Magnitudes

PSR B1620-26 has an apparent magnitude of 24.00 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 11.10 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.

Distance to PSR B1620-26

The Parallax of the star is given as 0.26 which gives a calculated distance to PSR B1620-26 of 12392.22 light years from the Earth or 3799.39 parsecs. It would take a spaceship travelling at the speed of light, 12392.22 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 783,674,981.48 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.
