The system's primary is small as well. At roughly 6% the mass of the Sun, it is probably too small to sustain fusion reactions, making it a dimly glowing brown dwarf.[3] Also, the estimated projected distance between MOA-2007-BLG-192Lb and its primary is approximately 0.62 astronomical units.[1] That means the planet probably formed with much ice and gases, more like Neptune (an ice giant planet) in composition than Earth (a terrestrial planet), according to astronomer David Bennett of the University of Notre Dame.[3]
