Galactic Center Region in Near-Infrared from Hubble
About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.17h 45m 36.0s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-28° 55' 58.8"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Sagittarius
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.26,000 light-years (8 kiloparsecs)
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.The image of the galactic center is 32.5 arcminutes (246 light-years or 75.5 parsecs) wide.
