A smaller fraction of all dust in space consists of larger refractory minerals that condensed as matter left the stars. It is called "stardust" and is included in a separate section below. The dust density falling to Earth is approximately 10−6/m3 with each grain having a mass between 10−16kg (0.1 pg) and 10−4 kg (100 mg)
