The Alternate Universe' Solar System

Rules: Planets must be the same to the naked eye.

Sun: A yellow star. Nuclear Fusion of Hydrogen into Helium emits a sort of aether. This aether can, with the correct material, be used as a wind for aether sails.

Mercury: a moon-like, tidally locked world with a thin oxygenated atmosphere and a tiny band of liquid water and land and flowers and things along the twilight band. The near side of Mercury is baked by the sun, and the far side is permanently frozen and covered in snow.

Venus: A world covered in thick white clouds that provide shade from the otherwise too-hot sun. The world is covered in rainforests, swamps, oceans, and volcanoes. Its atmosphere is 8 times as dense as the Earth's. It is inhabited by countless species of flora and fauna, including the Hocapans: a species of bird people.

Earth: A world covered with rainforests, deserts, mountains, oceans, oceans, oceans, plains, savannahs, and people.

Luna: A dead brown world with craters and a small amount of water.

Mars: A planet with red, iron-rich dirt, reddish plant life, and sparse blue oceans. Largely covered in deserts. Its thin atmosphere, 1/10 that of Earth's, holds less moisture and oxygen. It is inhabited by the Brasmons, large tripedal brains that are desperately trying to keep their planet from dying.

Phobos: a tiny asteroid rich water ice, making it a great refueling station.

Deimos: a tinier asteroid rich in water ice and metals.

1 Ceres: The smallest planet, Ceres is more or less a duller version of the Moon. It is the largest object in the asteroid belt, a region of minor planets that includes 1 Ceres, 2 Pallas, 4 Vesta, 10 Hygiea, and 87 Sylvia, to name the largest few. Some accounts describe Ceres as a minor planet or a dwarf planet, as its size is far smaller than that of the next largest planet, Mercury.

Jupiter: Jupiter is the largest planet in the solar system. It is covered in brown, red, and white bands of clouds, and has a 3-earth-sized storm on its southern equatorial band called the Great Red Spot. It is composed of hydrogen and helium gas. Floaters, Hunters, and Sinkers are some examples of life forms that exist in the clouds of the planet. Cities inhabited by descendants of Europans can be found here.

Io: A large moon about the size of Mars. It is covered in active volcanoes and lava flows, as well as a thin atmosphere and boiling liquid water oceans dot its otherwise yellow/brown volcanic surface. Ionian people are subjugated and enslaved by the Ganymedians.

Europa: A large moon around as big as Mercury. It is made out of ice, with a core of rock and iron. Inbetween the core and the surface of ice is an ocean of liquid water. Europan life forms, vaugely humanoid fish people, have a civilization here. An ancient civilization had managed to break the water technology barrier, and had explored the rest of the Jovian system before effectively disappearing.

Ganymede: A large moon about as big as the Earth. Its surface is dark brown with spots of white and pale brown, but underground caves heated by internal geological activity have given rise to liquid water and life forms. The Ganymedians now dominate the majority of Jovian system. They are xenophobic in the same way that polite Southern US citizens are racist. Polite, but secretly wishing you didn't exist.

Callisto: A large moon about as big as Venus, covered largely in ice. The planet is dead, but has been settled by Ganymedians.

Saturn: Saturn is the second largest planet in the solar system. It is yellow, brown, and subtly striped. It has a huge and densely packed system of rings, formed by the destruction of a metallic and ice rich moon.

Enceladus: A very small moon, colonized ages ago by the ancient Europans.

Titan: A Luna-sized moon with oil oceans and an abnormally thick atmosphere for its size. Oil rainforests, oil rivers, oil clouds. You name something that is water on Earth, there's an oily analogue on Titan. Even water/protein life is replaced with oil/lipid life. Titan is also inhabited by Titanians, which are a hive-minded creature who have built a civilization.

Other Major Moons of Saturn: Owned by Enceladeans and Titanians. This causes disputes and conflict.

Uranus: An ice giant planet.

Neptune: An ice giant planet.

Pluto: A Mars-sized planet

Charon: A Mercury-sized moon orbiting Pluto.
