How long does it take Pluto to orbit the sun? Learn more about how this planet makes one lap around our Solar System.

JWST finally detects radiation from Pluto that conclusively determines that Pluto's haze indeed impacts its climate.

New data captured by the James Webb Space Telescope has finally given astronomers new clues about how Pluto cools itself.

Simultaneously cooling Pluto while energizing atmospheric molecules to allow them to escape into space, Pluto's haze plays a ...

JWST has confirmed Pluto’s bizarre atmospheric behavior and its ghostly interaction with Charon. These findings could reshape ...

Science and technological advancement never ceases to amaze us year after year. Well, the group of astronomers working with the James Webb Space Telescope has brought to light a se ...

Its surface temperature averages around -387°F. At that temp, not only would your breath freeze mid-air, but even nitrogen and methane, gases here on Earth, can freeze solid on Pluto’s surface ...

Pluto was discovered 95 years ago. It has captured imaginations ever since. ... and features a surface temperature as low as -400°F. Still that date will be one to circle on cosmic calendars.

It has a methane, nitrogen and carbon monoxide atmosphere and a surface temperature of minus 378 to minus 396 degrees, too cold to sustain life. NASA sent its probe New Horizons on a flyby in 2015.

The first kind is water ice—because the temperature on Pluto sits so far below the freezing point of 32 degrees Fahrenheit, any water on the surface is rock solid.

For example, Charon’s collision with Pluto would have raised the temperature of the the dwarf planet’s ice shell, which may have caused it to melt and form a subsurface ocean.
