2.1×10¹⁸ m — 200 light years — Diameter of the Eta Carinae Nebula
3.1×10¹⁸ m — 310 light years — Distance to Canopus according to Hipparcos
4.0×10¹⁸ m — 430 light years — Distance to Betelgeuse according to Hipparcos
6×10¹⁸ m — 600 light years — Diameter of Omega Centauri (one of the largest known globular clusters, perhaps containing over a million stars)
