Kepler-725 c
Kepler-725 c is a confirmed sub-Neptune exoplanet 2,474 ly from Earth in the constellation Lyra, discovered in 2025 by Kepler.
Transit Timing Variations: inferred from the gravitational tug it puts on a sibling planet’s transit timing.
Standing on Kepler-725 c, you would weigh almost exactly what you weigh on Earth. Its yellow, Sun-like star looks 1.3× wider than ours, bathing the surface in warm white light. A year passes in just 208 days, and at an estimated -5°C (23°F) it is cold.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at 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 -5°C (23°F), sound would travel roughly 4% 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.
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.
- Surface temperatures near -5°C (23°F) fall in the range where liquid water is at least possible.
- Surface gravity is close to Earth's, 1.02 times, so you would move much as you do here.

What is the gravity on Kepler-725 c?
Kepler-725 c's surface gravity is about 1.0 times Earth's.
How much would you weigh on Kepler-725 c?
Someone who weighs 150 pounds on Earth would weigh about 153 pounds on Kepler-725 c.
How far is Kepler-725 c from Earth?
Kepler-725 c lies about 2,474 light-years from Earth.
How long would it take to get to Kepler-725 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 3.9 million years.
How hot is Kepler-725 c?
Kepler-725 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -5°C (23°F).
Is Kepler-725 c habitable?
Kepler-725 c 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-725 c?
Kepler-725 c completes one orbit of its star in 208 days.
