Class of stars Sub-brown dwarf
Brown dwarfs are not really stars, because there is no thermonuclear fusion in their core. These objects are smaller and cooler than stars, but too massive to be considered planets. Brown dwarfs of spectral class Y are the coolest and only a few of them have been discovered so far.
