Bet-3

Its story

Beta-3 Tucanae is part of a hierarchical sextuple stellar system in the constellation of the Toucan, every member belonging to the Tucana-Horologium association, one of the youngest stellar groupings near the Sun at just 45 million years. Infrared observations reveal a cold debris disc around it, leftovers from planet-forming processes. At 149 light-years, it pulses white and youthful among the feathers of the southern bird.
