Which is the coldest planet in our solar system!!
Uranus has an outer temperature of -224 degrees Celsius. It is colder than Neptune, as it lacks such a large moon as Neptune's Triton to heat it via tidal interactions. On Neptune, Triton's gravity warps the shape of the planet pulling "harder" on the face of Neptune closes to Triton (The farther away, the less gravitational influence), just like Earth's moon brings in the tides. This mechanically warping takes energy, draining the rotational kinetic energy of Triton, and ultimately converting it to heat. Uranus' largest moon Ariel is less than a tenth as massive as Triton, even though its a little bit closer to it's planet, and doesn't provide as significant tidal warming. This keeps Uranus colder, Even though Neptune is more than a billion miles farther away from the Sun, and ge ...more
