About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.20h 34m 14.11s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.41° 8' 3.54"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Cygnus
- 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.4,500 light-years (1,380 parsecs)

Note: Hubble data of IRAS 20324+4057 have been combined with ground-based H-alpha observations taken in 2003 with the Isaac Newton Telescope (INT) to create the composite image. This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: H-alpha Blue: F606W (V) Orange: F814W (I)
