“New Horizons”
The latest information and images

2. Recent Probe to Pluto
In 2015 the “New Horizons” space probe flew by Pluto giving us our first good images of its surface.
Including a large heart-shaped light colored region
The Tombaugh Regio
Or this “Icy spider” of fractures revealing a red material beneath the surface

3. Pluto’s Basic Stats Radius: 1,187 km (.186 of Earth)
Mass: 1.30 x 10²² kg ( of Earth)
Density: g/cm³
Surface Gravity: .620 m/s²
Orbit and Rotation
Distance to Sun: Aphelion: AU
Perihelion : 29.7 AU
Period (Year): 248 Earth Years
Day, Sidereal: Earth Days
Axial Tilt: 122.5º (Earth’s: 23.45°)
Name Origin: Roman God of Underworld

4. Pluto’s atmosphere
Before the “New Horizon’s” probe Pluto’s thin nitrogen atmosphere was thought to freeze back onto the surface when it was farthest from the Sun It turns out it doesn’t. The atmosphere stays there and may even become thicker when it is farther away.

5. Pluto’s Features Mapped
Pluto’s varied terrain includes Mountains and Plains

6. Composition and Internal Structure
The Plains of Pluto are 93% frozen Nitrogen The white parts of the Tombaugh regio have some Carbon Monoxide Ice Mountainous Ares are mostly Water Ice Radiation should have heated the interior enough to differentiate and creating layers Water Ice under the surface, and A rocky (silicate) Core

7. Pluto’s Moons Charon’s radius is about half that of Pluto (606km)
It is the biggest moon when compared to its planet in the solar system, so:
It and Pluto both orbit each other, a binary Dwarf Planet
The are tidally locked to each other
There are four small moons
Discovered in:
2005 Nix & Hydra
2011 Kerberos
2012 Styx
