Pluto
Pluto is a rocky world in our own solar system.
Standing on Pluto, you would weigh about 94% less than you do on Earth. From here the Sun looks 0.03× as wide as it does from Earth, bathing the surface in warm white light. A year here lasts 248 Earth years, and at an estimated -229°C (-380°F) it is colder than almost anywhere in the solar system.

If your children grew up herea playful thought experiment
Barely any weight to fight, at 0.06 times Earth's gravity. A child who grew up here could grow remarkably tall and willowy, about 1.7x taller than on Earth: a 5 ft 10 in adult could stand nearer 10 ft 2 in, with long thin limbs and delicate bones that never had to bear much load.
- Bones
- Light and slender
- With little weight to carry, the growing skeleton lays down far less bone, the way astronauts' bones thin in months of low gravity.
- Heart
- Unhurried
- With less weight pulling blood down toward the feet, the heart has far less work to do.
- Movement
- Bounding and springy
- So little weight means each step would carry the body up and forward in long, floating strides.
A playful thought experiment from this world’s gravity, not a prediction about any real person. No human has ever grown up off Earth, so no one truly knows; the direction (taller in low gravity, shorter and stockier in high) follows how growing bodies respond to weight.
Hear how a voice sounds herea computed acoustic demo
You would hear nothing at all.
With essentially no atmosphere, there is no medium to carry sound. You could shout into someone's helmet from an inch away and they would hear nothing: space is silent.
- !A cryogenic dwarf world near -230°C, cold enough to freeze nitrogen onto the ground.
- !Its thin haze of an atmosphere freezes out completely as it drifts farther from the Sun.
- !Daylight is roughly a thousandth of Earth's, a dim twilight at best.
A playful read of Pluto’s measured and computed values, not a real advisory.
Pluto is in our own solar system. It orbits about 39.48 AU from the Sun, so sunlight reaches it in roughly 328 minutes. From Earth it is about 38.48 AU away at closest, and a spacecraft is far slower:
How long to get there with today’s craft
At the speed of the Parker Solar Probe, the fastest craft ever built, the trip to Pluto would take about 346 days; a real mission took New Horizons nine and a half years, the fastest launch ever flown.

What is the gravity on Pluto?
Pluto's surface gravity is about 0.06 times Earth's.
How much would you weigh on Pluto?
Someone who weighs 150 pounds on Earth would weigh about 9 pounds on Pluto.
How hot is Pluto?
Pluto's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -229°C (-380°F).
How long is a year on Pluto?
Pluto completes one orbit of the Sun in 248 years.
