This is ceres, or also known as 1 ceres. It IS in the solar system. also just watch. Ceres was the first object discovered in the asteroid belt, giving it the name; "1 Ceres." It is pronounced "series". Ceres is made up of mostly water ices, silicates, and other similar materials. This little world may be one of humanity's future homes. Sense it is in the asteroid belt, there will be other asteroids to get minerals from, making it ideal for a mine. Not just that, it has stuff such as helium-4 and water on and in it, therefor making it a good galactic gas station!
