Alsephina

Roughly 81 light-years away, Alsephina is among the nearer bright stars catalogued in the southern constellation Vela, where it holds the Delta designation. Classified as a white A-type star, it has a colour index near zero (0.043), the near-neutral tint typical of stars in this temperature range. Its apparent magnitude of 1.93 places it just at the threshold of the constellation's brightest members. Because it lies relatively close, its absolute magnitude of −0.03 — a measure of true output — is only modestly brighter than its apparent figure would imply for a more distant object. That near-equality of apparent and absolute brightness is itself a sign of the star's comparative nearness. Together, its proximity and intrinsic brightness keep Alsephina a fixed naked-eye landmark of the southern sky.
