As the question states, how does the size of the Death Star compare with the Yorktown space station featured in Star Trek Beyond?

    I'm voting to close this question as off-topic because it's a gorilla vs shark question

    I'm asking about the relative size of both stations as while there is a lot of information about the size of the death star there is little information about the size of the Yorktown base Sep 22, 2016 at 20:20

    @ATB Although the two objects appear in different universes, it's possible that this question is objectively answerable. If the sizes of both objects are known according to some common measuring system (e.g. metres or tonnes), then it's not gorilla vs shark. See also this post about the policy on GvS questions.

    I'm voting to leave open for the reasons pointed out by @Rand

    @mooz - The question is objectively answerable since the OP is asking about the measurements and since those measurements can be confirmed out-of-universe.

This is a graphical depiction of how the two objects would look side-by-side, based on the best canonical evidence we have about their sizes.

enter image description here

According the the concept artist for Star Trek Beyond, Sean Hargreaves, the outer diameter of Yorktown Station is 40 miles.

Q. Do you remember how big Yorktown is supposed to be.

Sean Hargreaves: About 40 miles in diameter at the outer glass sphere.

By comparison, the canonical size of the Death Star (the first one) is 75 miles in diameter. The Second Death Star is 99 miles in diameter.

    Are all the light sources on the Death Star windows? Just how big would those windows have to be to be visible on a station that size?

    Considering the size of the thing, and the quantity of bright spots on the equator, they're more likely to be landing bays or other massive doors than windows... Unless they're deck-spanning panoramic windows, anyway.

    I've changed this for the accepted answer because it makes more sense for the whole diameter of the yorktown station to be bigger than it's arms as confirmed by the sources you included Sep 23, 2016 at 14:16

    @Ryan - According to his biography, his eating these is something of a myth. He once flew to Denver to get one after he was told that they were good. History doesn't record if he ever ate another one.

According to Sean Hargreaves, the designer of the Yorktown, each arm is intended to be 17.5 miles long and they open into the interior ball. This means the radius of the station is a little bit more than 17.5 miles or 28.16 km.

The death star, is said to have a diameter of 87 miles (DS1), or 99 miles(DS2). Both are significantly bigger than the Yorktown.

In fact, if you want to compare it in size to another Star Wars battlestation/large object, it's a bit bigger than the star forge, which has a radius of 25 km

    Alas, you've failed to take into account that there are two arms extending from the outer hub, plus a gap between the arms and the outer wall.

  • @Valorum I was going off of known value and making a rough estimate based off of that. The gap and the ball inside combined are significantly less than one of the arms. That's why I said a 'little bit more' where a little bit is a approximately 2.5 miles more.

    You may wish to also note that your figure of 87 miles comes from the (non-canon) Star Wars Enclyclopedia
