Kepler-1636 b

Kepler-1636 b is a confirmed sub-Neptune exoplanet 6,352 ly from Earth in the constellation Cygnus, discovered 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-1636 b, you would weigh roughly almost exactly what you weigh on Earth. Its yellow, Sun-like star looks about the same size as ours, bathing the surface in warm white light. A year here lasts 425 days, and at an estimated -25°C (-13°F) it is cold.

Gravity close to Earth's, at about 1.0 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 -25°C (-13°F), sound would travel roughly 7% slower 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 -25°C (-13°F) fall in the range where liquid water is at least possible.
  • Surface gravity is close to Earth's, about 1.01 times, so you would move much as you do here.

Common questions

What is the gravity on Kepler-1636 b?

Kepler-1636 b's surface gravity is about 1.0 times Earth's, estimated from its size.

How much would you weigh on Kepler-1636 b?

Someone who weighs 150 pounds on Earth would weigh about 151 pounds on Kepler-1636 b.

How far is Kepler-1636 b from Earth?

Kepler-1636 b lies about 6,352 light-years from Earth.

How long would it take to get to Kepler-1636 b?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 9.9 million years.

How hot is Kepler-1636 b?

Kepler-1636 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -25°C (-13°F).

Is Kepler-1636 b habitable?

Kepler-1636 b orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.68. That makes it worth studying, but it is not evidence of life: we have no measurement of its atmosphere, water, or surface.

How long is a year on Kepler-1636 b?

Kepler-1636 b completes one orbit of its star in 425 days.
