Sci-Fi Spaceship Lengths

Ever wondered how long Darth Vader's Super Star Destroyer The Executor is? Almost 20 km! Compare the lengths of spaceships across many different sci-fi series at Starship Dimensions.

Compared to The Executor, most of the other ships don't even match up. The rod-like spaceship Discovery in 2001: A Space Odyssey is only about 113 m in length. The regular imperial star destroyers are only about 2 km in length, though. The size disparity is clear in the picture.

And of course, if you remember the scene from the ROTJ where Admiral Ackbar says to "concentrate all fire-power on that super star-destroyer" before The Executor crashes into Death Star II, it's no surprise that the spacestation could contain a few hundred thousand super start destroyers.

I was, howewer, surprised to find out that the Death Star II had a radius about five times that of the first Death Star. While the original Death Star had an impressive radius of 160 km, the Death Star II trumps that with a whopping 800 km radius! Incidentally, that's only slightly short of the radius of Pluto which is 1180 km. And considering that there are several well-known moons in our solar system that are smaller than the first Death Star, Han Solo's characterization of it as "a small moon" seems justified as well.
