This is the very first planet that formed, Caper and it's four moons Io, Dao, Taseo, and Lent. There actually used to be a fifth moon named... I can't remember, not sure if it was named actually.
Caper is the first planet to form and get caught by the sun's orbit, It's mass is 51.2 earths and has a high density of 9.43 g/cm³, it's gravity is at 5.32 earths surface gravity. Pretty intense. It's orbit is 239 years. Not sure how the planet got so dense but it has a strong pull on it's moons.
Io and Dao are falling inward while Taseo and Lent are very very slowly falling outward. It's a fast process on a universal scale, but its still slow to us of course.
Io was the first moon named since Io is my favorite moon name. Its red and is very small to Caper with a mass of 0.092 moons and a gravity of 0.0012 earth's surface gravity. It takes 11.1 days to orbit Caper.
Taseo is the second one, it's got a pale green color to it and is much larger than Io at the size of 0.94 moons. (I'm going off of Universe Sandbox's scale of mass btw). It's orbit takes 24 days.
Dao is the largest of all the moons at 3.68 moons. It's a pale yellow color. It takes 53.1 days to orbit Caper.
Lent is the last and furthest moon. It's smaller than Dao and Taseo at 0.20 moons. It takes 69.6 days to orbit Caper. I'm guessing that it will fall out of orbit within the next seven hundred or so years.
The image is at my website, since It doesn't seem to work here, there is an image showing the planet and moons at a larger scale, then at actual scale.
