It is a dense, compact stellar remnant no longer generating energy and has equivalent to about 68% of the Sun's mass but only 1% of its radius. Bret Feinblatt suggests Iota Centauri, a white A2 star about 66 LY from Earth, as a good candidate. During the debate, Shapley also used van Maanen’s observation of M81’s rotation as part of his argument for spiral nebulae being part of our own galaxy. According to Robert Burnham, Jr., Van Maanen's Star has a computed diameter of about 7,800 miles (just under the Earth's diameter of 7,930 miles), which results in a density of about 20 tons to the cubic inch, or about 10 times the computed density of Sirius B, the closest known white dwarf. C the distance light travels in a year. At a distance of 14.1 light-years it is the third closest of its type of star after Sirius B and Procyon B, in that order. Teegarden's Star appears to be a very dim, red dwarf star of spectral and luminosity type M6.5 V . Nuclear fusion has now ceased, and in the absence of radiation pressure the core has collapsed to a tiny fraction of the diameter of the original star, heating it up greatly before it begins its slow cooling down phase. 113. Even more rarely, a star can be named after an important figure in history. But the star is so faint you that need a telescope to see it; the Sun emits more light in 24 hours than this feeble star does in 15 years. According to Robert Burnham, Jr., Van Maanen's Star has a computed diameter of about 7,800 miles (just under the Earth's diameter of 7,930 miles), which results in a density of about 20 tons to the cubic inch, or about 10 times the computed density of Sirius B, the closest known white dwarf.
