What Is The Gravity On Pluto Compared To Earth?
Ever wondered what it would be like to step onto the surface of Pluto? Prepare to experience a weightless sensation like never before.
The gravity on Pluto, is a mere fraction of what you’re used to here on Earth. While our planet boasts a gravitational force of approximately 1 g, Pluto’s gravity is a meager 0.063 g, a mere 6% of what you’re accustomed to. This means that objects on Pluto weigh significantly less than they do on Earth.
But that’s not all. If you were to take a leap on Pluto, brace yourself for a surreal experience. The reduced gravity would send you soaring through the air, allowing for higher jumps and longer hang times compared to our home planet.
So, if you’re ready to delve into the fascinating world of Pluto’s gravity, buckle up and prepare for a journey like no other.
Key Takeaways

Bulk Parameters Comparison
When comparing the bulk parameters of Pluto and Earth, it’s evident that there are significant differences in mass, volume, density, and radius.
Pluto, classified as a dwarf planet by the International Astronomical Union (IAU), has a mass of 0.01303 x 10^24 kg, while Earth’s mass is 5.9722 x 10^24 kg.
In terms of volume, Pluto’s size is considerably smaller with 0.702 x 10^10 km^3, compared to Earth’s much larger volume of 108.321 x 10^10 km^3.
The mean density of Pluto is 1854 kg/m^3, making it less dense than Earth at 5513 kg/m^3.
Additionally, the equatorial radius of Pluto measures 1188 km, whereas Earth’s equatorial radius is 6378.1 km.
These differences in mass, volume, density, and radius contribute to the variation in gravity experienced on the surface of these celestial objects. On Pluto, the gravity is only 0.063 g or 2.03 ft/s^2, which is about 6% of Earth’s gravity.
These findings were determined through scientific research conducted by the University Applied Physics Laboratory at Johns Hopkins University Applied.
Orbital Parameters Examination
By examining the orbital parameters of Pluto and Earth, valuable insights can be gained into the dynamics of their respective orbits around the Sun and the gravitational interactions that shape their paths. Here are some key aspects to consider:
- Semimajor axis: The average distance from the Sun to Pluto is about 39.5 astronomical units (AU), whereas for Earth, it’s approximately 1 AU.
- Orbit period: Pluto takes around 248 Earth years to complete one orbit around the Sun, while Earth completes its orbit in about 365.25 days.
- Perihelion and aphelion: Pluto’s closest approach to the Sun (perihelion) is about 29.7 AU, while its farthest distance (aphelion) is approximately 49.3 AU. In contrast, Earth’s perihelion is about 0.98 AU, and its aphelion is around 1.02 AU.
- Eccentricity: Pluto’s orbit is more elliptical with an eccentricity of 0.25, while Earth’s orbit is nearly circular with an eccentricity of about 0.017.
Examining these orbital parameters provides a deeper understanding of the unique characteristics of Pluto’s orbit compared to Earth’s.
This knowledge is crucial for space missions, such as New Horizons’ exploration of Pluto and Charon, and for studying the dynamics of celestial bodies within our solar system.
Observational Parameters of Pluto
The observational parameters of Pluto reveal valuable insights into its unique characteristics within our solar system. By studying these parameters, scientists have gained a better understanding of Pluto’s surface, distance from Pluto, low gravity,
Pluto’s mass, Pluto’s surface, Pluto’s moons, and the gravity of Pluto compared to Earth.
| Observational Parameters | Pluto | Earth |

Comparison With Other Moons of Pluto
When comparing Pluto to its five known moons, one can observe distinct differences in size, shape, and orbital proximity.
The largest moon, Charon, is about half the size of Pluto and orbits it closely. On the other hand, the other four moons, Nix, Hydra, Kerberos, and Styx, are smaller and irregularly shaped. These moons are named after mythological figures associated with the underworld.
Unlike some other celestial bodies, Pluto does not have any known rings. To provide a visual representation of the differences between Pluto and its moons, the following table illustrates their characteristics:
