The solar system lost its ninth planet back when Pluto was demoted to a dwarf planet, but research might indicate that there ...

Pluto has long been one of the most debated celestial bodies in our solar system. Once classified as the ninth planet, it was ...

As Pluto is finally added to the University of Arizona's scale model solar system, a new study suggests how the dwarf planet's cold heart was originally broken.

Pluto hasn't been a planet for almost 20 years. In the early 2000s, scientists discovered several objects of a similar size to Pluto. So, during the summer of 2006, members of the International ...

Though Pluto has formally been considered a dwarf planet for almost two decades, it still has many lessons left for planetary scientists — including hints about how the solar system formed.

Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto ...

On Episode 176 of This Week In Space, Rod Pyle and Tariq Malik are joined by Alan Stern to talk about what is next in deep ...

On July 14, 2015, NASA's New Horizons spacecraft arrived at Pluto for the first time. The craft flew within 7,700 miles of the planet and is sending back reams of data and the highest resolution ...

We consider the joint tidal-thermal evolution of the system by combining a comprehensive tidal model that incorporates a viscoelastic tidal response with a parameterized convection model developed ...

Our model indicates that, with NH 3, the mean temperature of the mantle of Pluto is at the eutectic and its Ra ~ 10^4. The presence of NH 3 dramatically increases the vigor of convection for the two ...
