How Many Earths Can Fit In Uranus.
The distance between Earth and Uranus is around 63 million kilometers. If Earth was as large as Uranus, then 63 Earths could fit inside. Similarly, Uranus is about four times as wide as Earth. Here’s a NASA image to help visualize the ratios.
Unlike Earth, Uranus has no surface, so a spacecraft would need to sink through its upper atmosphere to reach its liquid icy center. The color of the surface of Uranus comes from the light from the Sun reflecting off the ice. The orbit of Uranus is 248 years long, while the orbit of Pluto is 30 astronomical units closer to the Sun.
The moons of Uranus are composed of rock and water ice. Many giant planets have named their moons after characters from ancient Greek and Roman mythology. However, the moons of Uranus are named after authors such as Alexander Pope and William Shakespeare. There are 27 known moons of Uranus. The moons are surprisingly small for a planet so far from the Sun. Each of the five largest moons of Uranus has a smaller surface area than Australia.
Although Uranus has been viewed by humans multiple times throughout history, no observers recognized it as a planet until the 18th century. Hipparchos, in 128 BC, recorded Uranus as a star, and John Flamsteed made the same mistake in 1690.
Scientists think that impacts may have caused Uranus to be tipped on its side. It also rotates clockwise, unlike most of the other planets in the Solar System. The orbit of Uranus lasts about 84 Earth years. Its next flyby will occur in January 2022.
As a planet, Uranus is about 63 times bigger than Earth. Its elliptical orbit means it can reach a minimum and maximum distance from the Sun. The resulting gap between Uranus and Earth is approximately 10 billion light years apart.
During the early evolution of the Solar System, Uranus probably formed close to the Sun. But it later moved to the outer part of the Solar System and is now a distant planet. It has three layers: an iron-nickel core, an icy mantle, and an atmosphere of hydrogen and methane. It is believed that over 80 percent of the planet is made of hot and dense fluids.
