Cha 110913-773444 (Cha 110913 for short) is an astronomical object surrounded by what appears to be a protoplanetary disc. There is no consensus yet among scientists whether to classify the object as a brown dwarf (with planets) or a planet (with moons). It is even smaller than OTS 44 which had been the smallest known brown dwarf prior to the discovery of Cha 110913-773444.

Cha 110913-773444 was discovered by Kevin Luhman and others at Pennsylvania State University using the Spitzer Space Telescope and the Hubble Space Telescope, as well as two earthbound telescopes in Chile.
