we would all die
Pluto is not a planet so that would be Mercury is 13.72% smaller. Venus is 0.23% smaller. Mars is 9.42% smaller. So that means 3 planets are smaller than Earth.
The Earth would be the coldest if it was the furthest from the sun. As things stand it is actually Uranus. Uranus is colder than Neptune because of it's core temperature The core of Uranus is at around 4737 °C (8559 °F), while the core of Neptune is at around 7000 °C (12632 °F).
The planets are always moving as they orbit the sun, so this answer keeps changing. For example, when Uranus and Neptune are on the same side of the sun, and Jupiter is on the opposite side, then Uranus and Neptune would be closest. However, if Neptune were on the far side of the sun, then Uranus and Jupiter would be closest. When Uranus and Neptune are at their closest, they're separated by (rough numbers) about 9 AU. When Uranus and Jupiter are at their closest, they're separated by (again, roughly) 13 AU. However, while Uranus and Neptune can be closer together than Uranus and Jupiter can, they can also be further apart.
The diameter of the planet Uranus is 51,118 kilometers.The diameter of the planet Neptune is 49,528 kilometers.So then it would be:1,590 c:
Neptune and Uranus. It would be Pluto and Neptune but pluto is no longer a planet it is a dwarf planet
Neptune does not have a known twin in our solar system. Its closest "twin" in terms of size and composition would be Uranus, which is a similar ice giant planet.
Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, (Eris, Pluto, Ceres)
Since it is so cold at Uranus any living being on Earth (humans pretty much, duhhh) would freeze in an instant
It is believed that there were eight planets before Earth in our solar system: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune.
The planets in order starting at the sun: Mercury, Venus, Earth, Mars - (the Inner Planets) Jupiter, Saturn, Uranus, Neptune - (the Outer Planets) Pluto is no longer considered a planet.
Neptune is expected to have the lowest surface temperature among Uranus, Saturn, and Neptune. This is due to Neptune's farther distance from the sun compared to Uranus and Saturn, resulting in less solar energy reaching its atmosphere.
The planets that are not classified as terrestrial are Jupiter, Saturn, Uranus and Neptune. If you count Pluto as a planet then it would be a part of that list as well. Mercury, Venus, Earth and Mars are the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the gas giants. Pluto is a dwarf planet.
