Viridus is 0.86 Earth masses, feel free to do the math/comparing to figure out the other ones masses because I don't wanna. Info on Viridus: Thick emerald green atmosphere but white ice surface, has three moons, Lapis, Lux, and Casia, was ejected from its system in the "late proto-planet era" Info on Lapis: No atmosphere, formed by Lux but stolen from Lux and pulled into Viridus's orbit due to Viridus's gravity, very cratered surface. Info on Lux: Thick tan/orange atmosphere but gray rocky surface, most reflective of the moons (when there's a star to give it light near by), impacted an old Lapis sized moon of Viridus long ago to form Lapis, is largest moon of Viridus. Info on Casia: No atmosphere but purple/amethyst surface, was a dwarf planet that got captured by Viridus's and Lux's gravity whist Viridus was passing through a system.
Viridus was ejected from its system by an almost brown dwarf during the "late proto-planet era" (that era is when the planets are mostly stable except for a few). When it got ejected due to gravity its two moons, Lux, and Vetus Petram, were forced to follow. After millions of years Lux and Vetus Petram collided causing Lux to form a sub-moon names Lapis, which was immediately gravitated into orbit of Viridus. After passing though many system over millions of years, Viridus's and Lux's gravity captured a dwarf planet into orbit of Viridus in one particular system, the dwarf planet was similar in size to Lux and is named Casia. In this journey through the system that Viridus captured Casia in, Lapis got even more craters from the asteroid belt Casia orbited in.
