About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    11h 49m 35.08s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    22° 24' 10.94"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Leo
  • 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.
    9.3 billion light-years or 2.9 billion parsecs (supernova); 5 billion light-years or 1.5 billion parsecs (cluster)
