Helium-3



Helium is a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas group in the periodic table and whose atomic number is 2. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions. Accumulated in a number of ice asteroid fields around Sirius, helium is required for a number of industries along with neon, and is mined in small to medium quantities by independent suppliers.
