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.
Sand star
The sand star has a small disc and five long, flattened arms with tapering tips. It can grow to a diameter of , and is a grey, greenish-grey, or pale brown colour, sometimes speckled with white. The arms have rows of large marginal plates, each with several spines, but these are not visible from the aboral (upper) side. The tube feet have no suckers, but instead end with blunt points. The sand star could be confused with "Astropecten verrilli", but in that species, the large marginal plates are visible from above. This starfish seems to be easily damaged, and often breaks in pieces if raised from the seabed by trawling. Even when brought up intact, it often has missing or regenerating arms, perhaps the result of attacks by predatory crabs or fish.
