About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.13h 11m 34.19s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-1° 21' 56.0"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Virgo
- DistanceDistanceThe 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 color image of Abell 1689 is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (g) Green: F625W (r) Red: F850LP (z)
