[Star Wars] Would having a Death Star in orbit affect a planet's tides?
gpt
The first Death Star had a radius of about 60km. The volume would be about 11000 km3. Our moon has a radius of about 1737km. The volume of the moon is around 22000000000 km3. Also we see lots of empty space within the Death Star in forms of corridors, rooms and the vast space to hold the generators and laser. We can assume it is much less dense than the moon. Therefore the mass of the Death Star is virtually nothing compared to the Moon.

So would having a Death Star in orbit effect a planet's tides? Probably not. The extra gravity pulling on the oceans would be too little to measure with anything but the most precise instruments.
