Until it lost its planetary status in 2006, Pluto was the coldest with an estimated surface temperature between -235 and -210 degrees Celsius. But Pluto has now been relegated the status of a Dwarf Planet.
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 gets less sunlight.
The temperature on the distant Kuiper Belt dwarf planets should be practically absolute zero, since they get virtually no solar or internal heating. Haumea, Makemake, and Eris are locked in a frozen state like Pluto.
Mercury Hot and Cold
Interestingly, since Mercury rotates so slowly, at night it cools down to -183 degrees Celsius. Not quite as cold as Uranus or Neptune, but very chilly! Since it reaches 630 degrees Celsius on the sunward side, even 88 Earth days in shade can't cool it completely.
Uranus is the coldest planet in the solar system.
Comment: That's just about right, but Neptune is more or less at the same temperature.
Uranus. But Neptune is very nearly as cold.

What is the smallest darkest coldest planet?
Pluto is the smallest and the coldest planet in the whole Solar System.
Is Jupiter the fourth coldest planet?
Jupiter is not the fourth coldest planet the fourth coldest planet is my private jet because i got big balls and i say so -Pedro Veloz -hahahaahhahaha lolz naw sike Jupiter is the coldest fourth planet in the solar system>
Is uranus the seventh coldest planet?
Yes, Uranus is the seventh coldest planet in our solar system. Its upper atmosphere is typically around -224 degrees Celsius, making it one of the coldest planets.
Is Uranus the coldest planet is your solar sistom?
Is Uranus the coldest planet in OUR solar SYSTEM is actually how you should write the question. Pluto used to be the coldest planet in the solar system with an average -235 to -210 degrees Celsius! But since Pluto was classified as a dwarf planet since 2006 it no longer counts as one of the planets in our solar system. So Uranus IS the coldest planet with -224 degrees Celsius.
One planet appears to be both one of the hottest and coldest planets in the solar system?
Mercury -during the day it is very hot -at night it is very cold because of its slow rotation

Is Moon coldest planet in the universe?
Moon is not a planet - It is a satellite. Several planets in our solar system have moons (one or more) that happen to have names. Our moon doesn't have one. The coldest planet in our solar system used to be Pluto until it was demoted from the planetary status. Now it is Uranus.

Which two planets are the coldest?
Neptune and Pluto are the two coldest planets!
Is neptune one the coldest planet?
Because it is the last planet in are solar system, in other words, it's the farthest away form the sun. Hoped this helped!
Which planet has eleven moons and the coldest surface temperature?
Triton, one of Pluto's moons, is the coldest moon in the solar system. In second place is Charon, another one of Pluto's moons.
One planet appears to be both one of the hottest and coldest planets in the solar system?

A planet that's in your solar system?
Earth is one of the planets in our solar system.
What are the coldest planets?
Some of the coldest planets in our solar system are Neptune and Uranus, which are gas giants located far from the Sun. These planets experience extremely low temperatures due to their distance from the Sun and their thick atmospheres. Additionally, Pluto, though no longer classified as a planet, is also one of the coldest objects in our solar system due to its distance from the Sun.
Name the biggest the smallest the hottest and the coldest planets?
The biggest planet in our solar system is Jupiter, the smallest planet is Mercury, the hottest planet is Venus due to its thick atmosphere trapping heat, and the coldest planet is Neptune, located farthest from the Sun.
