Here are some of the most amazing discoveries that New Horizons has produced of Pluto

The dwarf planet is only two-thirds the size of our moon and resides more than 30 times farther out from the sun than does Earth .

Despite its frigid temperatures on the surface, Pluto has a roaring internal geologic engine.

Pluto constantly erases old blemishes and refreshes its exterior as remnant heat in the interior powers geological reshuffling.

No one expected Pluto to harbor a gassy sheath for a planetary body so tiny and distant.

The layers of the atmosphere are actually blankets of haze, which allow Pluto to hold onto its air.

Without this hazy atmosphere, Pluto’s volatile glaciers would have encountered the full brunt of the sun and frittered away into oblivion.

Pluto may be hiding a sloshy surprise roughly 125 miles beneath its shell.

Scientists suspect that a global ocean of liquid water is lurking right under the surface.

No direct evidence on the ocean exists to date, but scientists have inferred its presence in several ways.

Pluto also has large cracks on its surface, which can be explained by underground liquid water.
