The coldest planet used to be Pluto, but now that Pluto's not a planet anymore, the coldest planet is Neptune. Its cloud tops are at a freezing -218 degrees Celsius. That pretty cold, but it's recorded that one of Neptune's moons, Triton, has a record-breaking temperature of -235 degrees Celsius.
Also, isn't this weird? You know that Mercury rotates slowly, right? Well, at night it rotates so slow that its temperatures reach -183 degrees Celsius, although Mercury is the closest planet to the sun in the solar system. Not nearly as cold as Neptune, but colder than it would ever be here on Earth!
Anyways, if Pluto was still a planet, it would be the coldest, but not anymore. Now it's Neptune. Hope this helps!

∙ 11y agoVenus has the longest "sidereal day". One sidereal day on Venus is 243 Earth days. A sidereal day is the time for a planet to spin once.
There's another important definition of "day" and that's the "solar day".
The solar day is based on the position of the Sun in the sky and depends on a planet's orbit as well as its spin.
Using the solar day definition, Mercury has the longest day.
(On Earth, the solar day is exactly 24 hours and the sidereal day is about four minutes shorter.)
