- 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.About 3.6 Mpc (12 million light-years)
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.The visible portion of the HST M82 image is ~210 arcseconds (3.7 kpc) along the diagonal.
