  • 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.
    920 pc (5500 light-years)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    This image is 30 arcminutes square. The entire nebula is roughly 130 light-years across.
