Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a Supercritical fluid, supercritical phase of matter, which astronomy calls "ice" or Volatile ( ...

trojans have been discovered in Uranus’s Lagrangian point (leading Uranus).
was the first body to be classified as such a trojan in 2013, while in 2017 became the second.
Several theories have come to be on how such trojans could orbit Uranus.
Gravitational scattering is the most popular, stating that such asteroids (or
comets) could have been gravitationally pulled by the
other planets, leading them on a perfect trajectory towards Uranus, or somewhere where Uranus’s gravitational pull is
neutral.
