Which Planet is the Coldest?

The coldest planet in our solar system is Neptune.

Neptune is a very far planet from the Sun, which makes it really cold.
It is mostly made of gas and has strong winds, which can be very chilly.
Neptune has temperatures that can go down to -214 degrees Celsius! That's really, really cold.

Examples:

Imagine being outside in winter when it's very cold, but Neptune is even colder than the coldest day you can think of!
Neptune is so far that it takes a long time for sunlight to reach it, making it icy cold.
Even when the Sun is shining, Neptune stays frozen, just like ice cream in a freezer!

Fun Fact: Neptune is not only cold, but it also has beautiful blue colors because of the gases in its atmosphere!
