How long is Pluto's winter?

Answer 1

The length of a "solar day" on Pluto is determined by its axial tilt.

The planet takes 6.38 Earth days to rotate, and 249 Earth years to go around the Sun. But the tilt (60 degrees to the plane of its orbit) produces exaggerated seasons with some polar areas of the planet spending many Earth years in either the constant dim sunlight or constant darkness.

Answer 2

Pluto's winter lasts about 72 Earth years because Pluto's orbit around the Sun is highly elongated. This means that one season on Pluto, whether it's winter or summer, can last a long time compared to seasons on Earth.

Answer 3

The length of a day on Pluto is 6.4 times the length of a day on Earth or 153.3 hours long. This is because Pluto rotates slower than Earth.

Answer 4

Maybe.

Yes, because Pluto rotates.

However, it's so far from the Sun that even the "daytime" would be very dark.

Answer 5
