About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    12h 36m 55.36s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    +62° 12' 46.1"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Ursa Major
  • Distance
    DistanceThe 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.
    2.4 billion parsecs (8 billion light-years)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Redshift: z = 0.95
