About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    15h 59m 12.0s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    20° 45' 29.99"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Serpens
  • 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.
    190 million light-years (58 megaparsecs)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    This image is roughly 2.1 arcminutes (35 kpc or 114,000 light-years) in the vertical direction.
