Solar system: Double binary star(2 binary stars in a quadruple star system) Kepler A: A big blue star. It is bigger than all the other stars in the double binary system. It will however last longer than our sun just like the other 3 stars will. Kepler B: This is a green star(The green star is not false color or a binary star with a blue star and a yellow star). It is very rare to see a green star. It is in the same binary star as Kepler A is. It is cooler than Kepler A. It is also smaller. Kepler C: This is a much cooler red star. It is in the second binary star. It is the smallest of all the stars. Kepler D Kepler D is a white star. It is hotter than Kepler B but cooler than Kepler A. It is in the second binary star along with Kepler C Kepler Bb Kepler Bb is the size of Neptune but has an earth like atmosphere. The atmosphere is 4 times as thick as Earth’s. This is because Neptune is 4 times the size of earth and I thought “Why not have 4 be the magic number in this solar system?” Kepler Bb has 4 moons orbiting around it in different trajectories at different speeds but at the same distance. Rarely do 2 or more collide. Collision events are best seen at night or during the blue hour (The approximate 1 hour period between night and the beginning of starrise(Like sunrise but not referring to our sun) or between the night and the end of starset(Like sunset but not referring to our sun)) Multiple eclipses can also happen because of these 4 moons with different trajectories and different speeds. Again this is rare, especially when it involves a solar eclipse. Kepler B# Kepler B# is the size of Jupiter and also has an Earth-like atmosphere. Its year is different from that on Kepler Bb but like Kepler Bb it has seasons. It has 4 moons also but at different distances. Kepler Db Kepler Db is part of a binary planet system that orbits around the double binary star. It is more like Mars than earth but life is found here as well as on the 2 earth-like planets. Kepler D# Kepler D# is the other planet in the binary planet system. It is hotter than Kepler Db. In fact it is the hottest planet in the solar system. Since Kepler D# is the hottest planet in the solar system in my story and yet it orbits further away from the double binary star than the 2 earth like planets I was thinking that the source of all that heat would be a thick atmosphere of CO2 and other volcanic gases as well as lava itself I still have questions about this solar system Questions about Kepler D# 1) How many volcanoes would it have given that its atmosphere is much like that of Venus(That is thick with volcanic gas)? 2) How often would these volcanoes erupt? Once a day? Once a week? Once a month? Once a year? I am asking because if there is any life on Kepler D#, they would likely get their nutrients from lava and thus want to know when a nearby volcano is erupting. 3) Would there be any massive earthquakes from there being lots of active volcanoes? 4) Would the lava over time form bodies similar to our bodies of water as well as nutrient rich land? Questions about Kepler Db 1) Would there be any active volcanoes on this mars-like planet? 2) Would there be a lot of plants and herbivorous animals since plants love CO2 and a mars-like planet kind of implies that there is a lot of CO2? Questions about Kepler B# The civilization on Kepler Bb is like this: Every male makes a basic shelter for him and his future wife. Females have to either stay in one of their relatives' shelters or survive out in the open until they find the perfect husband for them. Once the female finds her perfect husband she lives with him for the rest of her life. Together they expand the shelter both on the surface and underground to have sleeping chambers, children's rooms, etc. These homes are connected underground. Homes are also connected to buildings this way and buildings are connected to other buildings this way. To keep the tunnels from forming a sinkhole the humaniods use static electricity. 1) Since this is an earth-like planet with the same humanoid species as Kepler Bb would the civilization be any different? 2) Would it have a Ring of Fire where most of the active volcanoes are?
