Kepler-1600 b

Kepler-1600 b is a confirmed sub-Neptune exoplanet 3,362 ly from Earth in the constellation Lyra, 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-1600 b, you would weigh roughly almost exactly what you weigh on Earth. Its yellow, Sun-like star looks 0.84× as wide as ours, bathing the surface in warm white light. A year here lasts 386 days, and it sits squarely in the habitable zone, among the more Earth-like worlds known.

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 deeper and fuller.

Assuming Earth-like air at this world's temperature of about -64°C (-83°F), sound would travel roughly 15% slower than on Earth, so your voice would sound deeper and fuller. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
★★★★
Recommended, with reservations
  • !Cold at about -64°C (-83°F), survivable only fully suited and heated.
  • Surface gravity is close to Earth's, about 1.02 times, so you would move much as you do here.
  • It orbits within the habitable zone, where a world could in principle hold liquid water.

Common questions

What is the gravity on Kepler-1600 b?

Kepler-1600 b's surface gravity is about 1.0 times Earth's, estimated from its size.

How much would you weigh on Kepler-1600 b?

Someone who weighs 150 pounds on Earth would weigh about 152 pounds on Kepler-1600 b.

How far is Kepler-1600 b from Earth?

Kepler-1600 b lies about 3,362 light-years from Earth.

How long would it take to get to Kepler-1600 b?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 5.2 million years.

How hot is Kepler-1600 b?

Kepler-1600 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -64°C (-83°F).

Is Kepler-1600 b habitable?

Kepler-1600 b orbits inside its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.61. 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-1600 b?

Kepler-1600 b completes one orbit of its star in 386 days.
