About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    13h 28m 25.99s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -19° 42' 29.99"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
