Why is Mars so cold?
Its atmosphere is rich in carbon dioxide (over 96%) and it is very dense. The atmosphere of Mars is also rich in carbon dioxide (above 96%), but it is extremely thin (1% of Earth’s atmosphere), very dry and located further away from the Sun. This combination makes the planet an incredibly cold place.

How cold does Pluto get?
-375 to -400 degrees FahrenheitThe temperature on Pluto can be as cold as -375 to -400 degrees Fahrenheit (-226 to -240 degrees Celsius). Pluto’s mountains can be as tall as 6,500 to 9,800 feet (2 to 3 kilometers) and are big blocks of water ice, sometimes with a coating of frozen gases like methane.
Can Planet 9 be a black hole?
So far, however, it has eluded discovery. Hence the suggestion that Planet 9 might not be a normal planet at all but a black hole. All known black holes were formed by collapsing stars or galactic-scale events; they are vastly more massive than any planet.
