The orbital radius of its XV-th moon is 7,473,290,240 km!!!
There is no way that this moon is almost as far from Dodixie VIII as Dodixie VIIII is from Dodixie! You have a bug in the formatting of the distance for the moons, most likely it is 7,473,290.240 km but instead of a decimal dot the game displays a thousand’s separator - a comma!
I wouldn’t be surprised if this is the actual distance. The cluster has a lot of weird celestial configuration, like one where the moon of a planet is 4x larger than the host planet.
No, it’s not. If you approach any moon of any planet and check the distance to the planet, it will be exactly 1000 times less than the displayed in the info window for that moon! And this is across the board in every system that I have visited recently and with every moon that I have checked. There are orbiting distances in the info window are 1000 bigger than they are.
The orbit radius of the moon around the planet is over 8 times the orbit radius of the planet around the sun. And it does so in only 35 days. That’s one speedy moon!
