Type of Object: The center of the Milky Galaxy probably contains a supermassive
(several million times the mass of our sun) black hole. The galactic center is called SGR-A*. The area surrounding SGR-A* contains emission of light from across the electromagnetic spectrum.
The center is obscured by dust clouds in the interstellar medium - so most of our observations are made in the near-infrared and radio parts of the spectrum.
Distance: 26,000 light years
Size: About 100 lyr across, depending on what
part of the spectrum you are observing in.
Coordinates (Epoch J2000):
Right Ascension: 17 45 12
Declination: -28 43 00.0
Other Names: Galactic Center, W 24
Radio Brightness at 1420 MHz (21 cm): 2000 Jy
