An oddity among Sol's gas giants, Uranus is mostly unexplored and uninhabited by humanity, as its distance from Sol makes traveling there costly. Its moons are poorly-understood when compared to those of Jupiter. Despite this, Uranus has a number of distinctive features that separate it from its neighbors. Firstly, its axial tilt has turned its poles past a 90o angle to the orbital plane. Secondly, Uranus has a number of anomalous radiation spikes that have not been addressed or explained.
