Comparing planetary systems. Artwork comparing the sizes of the 55 Cancri (a Sun-like system, left) and the Cha 110913-773444 (upper right) planetary systems. The latter, a small brown dwarf star system, has been studied with the Hubble Space Telescope and the Spitzer Space Telescope. Although the brown dwarf is a failed star, it is thought that the disk found surrounding it might one day form planets like those shown here. Cha 110913-773444 is only about eight times the mass of Jupiter, and is 500 light years away in the constellation Chamaeleon. This work was published in 2005.
