Pluto has roughly one-sixth the mass of the Moon and one-third of its volume. Originally considered a planet, its status was changed when astronomers adopted a new definition of the …

Apr 22, 2025 · Pluto's low gravity (about 6% of Earth's) causes the atmosphere to be much more extended in altitude than our planet's atmosphere. Pluto becomes much colder during the part …

Sep 28, 2025 · Indeed, for decades, such basic information as its radius and mass had been difficult to determine. It was not until Pluto was visited by the U.S. spacecraft New Horizons, …

What is the gravity on Pluto? The surface gravity on Pluto is about 1/12th the surface gravity on Earth. For example, if you weigh 100 pounds on Earth, you would weigh 8 pounds on Pluto.

There’s a lot we don’t know about Pluto, but one thing’s for sure: it’s very, very cold. Much too chilly to sustain life, but possibly suitable for a subterranean ocean at some point in the past.

As the smallest dwarf planet in our solar system, Pluto has the least gravity among the celestial bodies we will discuss. With a gravitational force of just 0.7 meters per second squared (m/s²), …

The gravity on Pluto is 7% than the gravity of Earth. An object weighting 200 pounds on Earth, would weight 14 pounds on Pluto. Before arriving at this conclusion, many astronomers and …

Feb 22, 2024 · Earth's robust gravity and thick atmosphere create a vastly different environment compared to Pluto's frigid, thin atmosphere. The surface of Earth supports diverse ecosystems …

Nov 3, 2025 · All three factors conspired to reduce Pluto’s influence on the New Horizons trajectory, resulting in a directional change for the spacecraft of a small fraction of a degree.

The giant planet's gravity can actually "slingshot" a spacecraft toward the outer solar system. There are two reasons why the New Horizons science team wanted to reach Pluto as soon as …
