About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    10h 45m 3.59s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.

  • 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.
    7,500 light-years (2,300 parsecs)

About the Data

  • Data Description
