Death Star
The first Death Star is depicted in various sources of having a crew of 265,675, as well as 52,276 gunners, 607,360 troops, 30,984 stormtroopers, 42,782 ship support staff, and 180,216 pilots and support crew. Its hangars contain assault shuttles, blastboats, Strike cruisers, land vehicles, support ships, and 7,293 TIE fighters. It is also protected by 10,000 turbolaser batteries, 2,600 ion cannons, and at least 768 tractor beam projectors. Various sources state the first Death Star has a diameter of between 140 and 160 kilometers. There is a broader range of figures for the second Death Star's diameter, ranging from 160 to 900 kilometers.
Star
With a mass only 80 times that of Jupiter (), 2MASS J0523-1403 is the smallest known star undergoing nuclear fusion in its core. For
stars with metallicity similar to the Sun, the theoretical minimum mass the star can have and still undergo fusion at the core, is estimated to be about 75 . When the metallicity is very low, however, the minimum star size seems to be about 8.3% of the solar mass, or about 87 . Smaller bodies called brown dwarfs, occupy a poorly defined grey area between stars and gas giants.
