Halley's nucleus is relatively small; barely 15 kilometres long, 8 kilometres wide and perhaps 8 kilometres thick. Its shape vaguely resembles that of an unshelled peanut. Its mass is relatively low; roughly 2.2 × 1014 kg, and its average density is about 0.6 g/cm3, indicating that it is made of large number of small pieces held together very loosely forming a structure known as a rubble pile.
