Our planetary system consists of four planets and their sun which is a type-G star. The sun's name is Sulfina and it is a main sequence star. Sulfina's luminosity is one and one-half that of Earth's sun. Its stellar mass is just slightly higher than the Earth's sun. Its average surface temperature is 6300(C).
Twylo is about one and one-half the mass of Earth and has slightly more gravity. Its climate is temperate, averaging 10.71(C). Its planet surface is 76% water. One day passes in slightly more than fourteen hours and a year is 592 days. The polar tilt of Twylo is 18 degrees. This makes little variation in weather.
Sulfina has four planets. The innermost one is Feldspar and it is too hot to allow life forms to live there. Although Feldspar has a diameter about one-third of Earth's, it is somewhat hollow and has a mass about 4% the mass of Earth's. It's more like a rock than a planet. Chrysalis is the next planet out; it has gravity about 70% of Earth's. It's about two-thirds the diameter of Earth and about one-third the density. Crysalis and Feldspar have no atmospheric pressure. Extron,the third planet out, is slightly larger and heavier than Earth. Extron's gravity is slightly stronger and its atmospheric pressure is 350 times as much as Earth's.
