This is a nice work (of fiction) here: as I irritated before Uranus is a Gas Giant there is no surface, yes admittedly it has a solid core you'd never get that far as the atmospheric pressure would kill you long before you got there.
Secondly while Uranus is blue due to methane crystals in its upper atmosphere that adsorb red light and reflect blue light back it has no oceans, Europa one of the moons of Jupiter is speculated to have one under its ice, as the surface is relatively young and has no impact creators; thus leading to the hypothesis that there is a liquid ocean there, however it should be noted that water has not been seen thus far I do not know weather a hydrogen spike has ever been detected on Europa. Titan, a moon of the gas giant Saturn has an ocean of liqud methane.
At the relative distance from the sun the sun would be small enough for you to cover it with your thumb instead of you hand as on earth. These details aside nice work.
Regards to you.
