    An eclipsing binary star is a binary star system in which the orbital plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. [20] In the case where the binary is also a spectroscopic binary and the parallax of the system is known, the binary is quite valuable for stellar analysis.

    en.wikipedia.org/wiki/Eta_Piscium

    Eta Piscium (η Piscium, abbreviated Eta Psc, η Psc) is a binary star and the brightest star in the constellation of Pisces, with an apparent visual magnitude of +3.6. [2] Based upon a measured annual parallax shift of 9.33 mas as seen from Earth, [1] it is located roughly 350 light-years distant from the Sun in the thin disk population of the ...

    VB 10 or Van Biesbroeck's star / v æ n ˈ b iː z b r ʊ k / [7] is a small and dim red dwarf [2] located in the constellation Aquila. It is part of a binary star system. VB 10 is historically notable as it was the least luminous and least massive known star from its discovery in 1944, until 1982 when LHS 2924 was shown to be less luminous. [ 8 ]
