Now, we learn in TNG 'Q Who' that the Borg Cube was capable of keeping up with the Enterprise-D at Warp 9.65 (Source). Its mass is just above the lowest limit (0.08 solar masses) at which a star is massive enough to ignite stable hydrogen burning in its core. [29] (Substellar objects below this limit are known as brown dwarfs.) It can be found close to the same path the Sun follows through the sky (the ecliptic), but can only be seen with a telescope. Wolf 359 is a flare star, a variable star of the UV Ceti type that can undergo sudden increases in brightness across the spectrum. Which are the Largest Stars in the Universe? [17] If these planets are confirmed, the setup of the system would be similar to but more extreme than that of nearby red dwarf Proxima Centauri, both having a close-in low-mass planet and a farther out higher-mass planet. The magnitude assumes nothing is between the object and the viewer, such as dust clouds. If Star X is 50 times as far from the sun as Wolf 359 is, how far is Star X from the sun, to the nearest light-year?
