Titan
Titan is a rocky world in our own solar system.
Standing on Titan, you would weigh about 86% less than you do on Earth. From here the Sun looks 0.10× as wide as it does from Earth, bathing the surface in warm white light. A year here lasts 29.4 Earth years, and at an estimated -179°C (-290°F) it is colder than almost anywhere in the solar system.

If your children grew up herea playful thought experiment
Low gravity, 0.14 times Earth's. A child who grew up here could become strikingly tall and lightly built, about 1.5x taller than on Earth: a 5 ft 10 in adult could stand nearer 8 ft 8 in, with long limbs and slender bones.
- 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
Your voice would sound deep and slow, dropped to a low bass.
Sound travels at about 199 metres per second here, roughly 41% slower than on Earth, so your voice would sound deep and slow, dropped to a low bass. The dense air would also carry every word loud and far.
A real voice sample, pitch-shifted (tempo held constant) to suggest the acoustics: a playful approximation, not a precise simulation. Voice: Lingua Libre / Vealhurl, CC BY-SA 4.0.
- !The only moon with a thick atmosphere, though it is unbreathable nitrogen and methane.
- !At about -180°C it rains liquid methane, with rivers and lakes of it on the surface.
- Thick air and low gravity mean you could in principle fly with strap-on wings, if you did not freeze first.
A playful read of Titan’s measured and computed values, not a real advisory.
Titan is in our own solar system. It orbits about 9.54 AU from the Sun, so sunlight reaches it in roughly 79 minutes. From Earth it is about 8.54 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 Titan would take about 77 days; a real mission took the Cassini probe almost 7 years to reach Saturn's neighborhood.

What is the gravity on Titan?
Titan's surface gravity is about 0.14 times Earth's.
How much would you weigh on Titan?
Someone who weighs 150 pounds on Earth would weigh about 21 pounds on Titan.
How hot is Titan?
Titan's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -179°C (-290°F).
How long is a year on Titan?
Titan completes one orbit of the Sun in 29.4 years.
