Together with the radial velocity, the total velocity can be calculated. Stars with high rates of proper motion are likely to be relatively close to the Sun, making them good candidates for parallax measurements. [145] When both rates of movement are known, the space velocity of the star relative to the Sun or the galaxy can be computed. Among ...

The final fate of the star depends on its mass, with stars of mass greater than about eight times the Sun becoming core collapse supernovae; [102] while smaller stars blow off their outer layers and leave behind the inert core in the form of a white dwarf. The ejection of the outer layers forms a planetary nebula. [103]
No, actually -- even NASA is calling this star the "loneliest" in the universe. "The unusual object, called CX330, was first detected as a source of X-ray light in 2009," according to a NASA news ...
Representative lifetimes of stars as a function of their masses The change in size with time of a Sun-like star Artist's depiction of the life cycle of a Sun-like star, starting as a main-sequence star at lower left then expanding through the subgiant and giant phases, until its outer envelope is expelled to form a planetary nebula at upper right Chart of stellar evolution
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
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 .
A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [76] AD ρ Cassiopeiae: 564 ± 67 or 700 ± 112 [77] AD
