The average surface temperature of Pluto is about -375°F (-225°C). While there may be slight variations due to its elliptical orbit, the difference between day and night temperatures is minimal.
Here's why:
* Distance from the Sun: Pluto is very far from the sun, receiving very little sunlight. This means the energy reaching Pluto is weak.
* Thin Atmosphere: Pluto's atmosphere is incredibly thin, providing little insulation to trap heat.
* Rocky and Icy Surface: The surface of Pluto is composed primarily of rock and ice, which are poor conductors of heat.
Therefore, Pluto's surface temperature remains consistently cold, even during its "daytime."
