Why are there moons at the edge of the solar system that cause their rotation axes to fluctuate as if ignoring the laws of ...

Those who supported Pluto’s demotion included Neil DeGrasse Tyson NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute Image 20 years ago, news broke that Pluto had ...

Twenty years ago Pluto lost its planethood, and I’m partially to blame. “Blame” is a strange word to use for what seems like a matter of mere semantics; after all, Pluto exists as an intriguing world ...

Evidence of the slowing of Charon's spin period (despinning) is recorded in tectonic features on the surface of Pluto's icy moon, according to a modeling study published in Nature Communications. The ...

The solar system’s icy moons are natural labs for astronomy’s most fascinating discoveries. And Charon, Pluto’s largest moon, is no exception. According to a new study, this icy world might redefine ...

The exploration of the outer solar system began in the early 1970s with the launch of Pioneers 10 and 11. These two, small spacecraft served as trailblazers for the larger missions that followed.

Pluto seemed hopelessly cold and distant until 2015, when NASA’s New Horizons space probe beamed back images of the giant heart-shaped mark that dominates the dwarf planet’s surface. Now researchers ...

Pluto and Charon don’t behave like a typical planet and moon system. Instead of Charon orbiting inside Pluto’s body, both objects orbit a point in space between them called the barycenter. That’s why ...

Pluto pulled Adeene Denton into its orbit during her undergraduate internship at the Lunar and Planetary Institute in Houston. It was summer 2015, when the New Horizons spacecraft zoomed past the ...
