Kepler-351 d

Kepler-351 d is a confirmed sub-Neptune exoplanet 3,535 ly from Earth in the constellation Lyra, discovered in 2016 by Kepler.

ESI 0.633,535 lyDiscovered in 2016 by Kepler

Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.

Standing on Kepler-351 d, you would weigh roughly about 6% more than you do on Earth. Its yellow, Sun-like star looks 1.5× wider than ours, bathing the surface in warm white light. A year passes in just 143 days, and at an estimated 45°C (113°F) it is warm.

much like Earth height

Gravity close to Earth's, at about 1.1 times. A child would grow up much as they would back home.

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 much as it does on Earth.

Assuming Earth-like air at this world's temperature of about 45°C (113°F), sound would travel roughly 5% faster than on Earth, so your voice would sound much as it does on Earth. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
★★★★
Recommended, with reservations
  • Surface temperatures near 45°C (113°F) fall in the range where liquid water is at least possible.
  • Surface gravity is close to Earth's, about 1.06 times, so you would move much as you do here.

Common questions

What is the gravity on Kepler-351 d?

Kepler-351 d's surface gravity is about 1.1 times Earth's, estimated from its size.

How much would you weigh on Kepler-351 d?

Someone who weighs 150 pounds on Earth would weigh about 159 pounds on Kepler-351 d.

How far is Kepler-351 d from Earth?

Kepler-351 d lies about 3,535 light-years from Earth.

How long would it take to get to Kepler-351 d?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 5.5 million years.

How hot is Kepler-351 d?
