The beginning of Uranus' formation began with solids and dust grains. A rotating cloud of gas and dust. Next came Core Accretion the process where planets grow from the particles surrounding the stars. Then began Disc Instability which contracts to create a flat disc with a star in its center. Afterwards came a progressive increase in the growth of the fluid bound nebula as the solid body grows rapidly.
Pluto is no longer considered a planet. It is too small, and does not meet the requirements that are required for a planet to be a planet. The diameter of Pluto is 2360 km. It fails one requirement that a planet must have a cleared neighborhood. This means it has become gravitationally controlling, and there are no other bodies of its size other than its own moons or those otherwise under its gravitational impact. A large body which meets the standards for a planet but has not cleared its neighborhood is classified as a dwarf planet. The qualifications for a planet to be a planet are: it needs to orbit around the sun, to have enough gravity to pull itself into spherical shape, and it must have a cleared neighborhood of its orbit. Pluto has all of the following except a cleared neighborhood.
Unlike Pluto Uranus is a planet. The diameter of Uranus is 51 118, much larger than Pluto. Uranus orbits the sun which takes it 84.3 Earth years to make a complete revolution. The gravity of Uranus is only 91% of the gravity on Earth. Uranus has a mass (quantity of matter) 14 1/2 times larger than Earth. The mass of Uranus is only around 1/20 as large as Jupiter.
The diameter of Uranus is 51,200 km. Approximately 20,635 Uranus' can fit into the Sun. Uranus is twenty times the diameter of Earth. Twenty Uranus' can fit into Jupiter!
