PSR B1620-26 b orbits a pair of stars.The primary star, PSR B1620-26, is a pulsar, a neutron star spinning at 100 revolutions per second, with a mass of 1.34 M ☉, a likely radius of around 20 kilometers (0.00003 R ☉) and a likely temperature less than or equal to 300,000 K.
A pulsar–neutron star system, e.g, PSR B1913+16. A pulsar and a normal star; e.g, PSR J0045−7319, a system that is composed of a pulsar and main-sequence B star. Theoretically, a pulsar-black hole system is possible and would be of enormous scientific interest but no such system has yet been identified.
PSR J2144−3933 is a pulsar about 180 parsecs (587 light-years) from Earth. It is the coldest known neutron star with a surface temperature less than 42000 Kelvin as measured by the Hubble Space Telescope. [1]
