About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    13h 11m 29.5s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -1° 20' 17.01"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Virgo
  • 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.
    The distance to the lensing cluster is 2.2 billion light-years (675 megaparsecs). The distance to the lensed galaxy is about 12.8 billion light-years.
