The Gamma Velorum system is composed of at least four stars. The brightest member, γ 2 Velorum or γ Velorum A, is a spectroscopic binary composed of a blue supergiant of spectral class O7.5 (~30 M ☉), and a massive Wolf–Rayet star (~9 M ☉, originally ~35 M ☉). [8]
AH Velorum is a Cepheid variable located less than a degree to the northeast of Gamma. [19] A yellow-white supergiant of spectral type F7Ib-II, it pulsates between magnitudes 5.5 and 5.89 over 4.2 days. [20] Also lying close to Gamma, [21] V Velorum is a Cepheid of spectral type F6-F9II ranging from magnitude 7.2 to 7.9 over 4.4 days. [22]

Prominent examples of stars in this mass range include Antares, Spica, Gamma Velorum, [2] Mu Cephei, and members of the Quintuplet Cluster. [3] Type Ia supernova progenitors are white dwarf stars that are close to the Chandrasekhar limit of about 1.44 solar masses and are accreting matter from a binary companion star.
Below there are lists the nearest stars separated by spectral type.The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O.It may be later expanded to other types, such as S, D or C.

In Chinese, 天社 (Tiān Shè), meaning Celestial Earth God's Temple, refers to an asterism consisting of Kappa Velorum, Gamma 2 Velorum, b Velorum and Delta Velorum. [16] Consequently, Kappa Velorum itself is known as 天社五 (Tiān Shè wǔ), "the Fifth Star of Celestial Earth God's Temple". [17]
Underwater archaeologists dug under 20 feet of sand and rock off the coast of Sicily and found a 2,500-year-old shipwreck. Researchers date the find to either the fifth or sixth century B.C.
