Because the solar system is in constant motion, the distance between Earth and Uranus changes daily. The closest the two get is 1.6 billion miles (2.6 billion kilometers). At their farthest, they are separated by 1.98 billion miles (3.2 billion km).
Astronomers use another term called âastronomical unitsâ to measure distance within the Solar System. 1 astronomical unit, or AU, is the average distance from the Earth to the Sun â about 150 million km. So in astronomical units, Uranus is an average distance of 19.2 AU. Its perihelion is 18.4 AU, and its aphelion is 20.1 AU. We have written many articles about Uranus for Universe Today.
