subject | fact |
Cygnus X-3 | is a part of Cygnus | |
has distance 10 kpc | ||
has synonym 2U 2030+40 | ||
has discovery date 1966 | ||
has orbital period 4.8 hour | ||
has definition An X-ray binary. It is also an infrared source, a cosmic ray source, and a strongly variable radio source (interstellar extinction is too high for visible light observations). It is best fitted by a model of an expanding cloud of relativistic electrons emitting synchrotron radiation around a neutron star. | ||
