DMPP-6 b

DMPP-6 b is a confirmed sub-Neptune exoplanet 178 ly from Earth in the constellation Volans, discovered in 2026 by Multiple Observatories.

Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.

Standing on DMPP-6 b, you would weigh roughly about 12% more than you do on Earth. Its yellow-white star looks 16.3× wider than ours, bathing the surface in bright white light. It is likely tidally locked, so that sun never moves in the sky: one hemisphere in endless day, the other in permanent night. A year passes in just 7.6 days, and at an estimated 931°C (1707°F) it is hot enough to melt rock.

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 high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 931°C (1707°F), sound would travel roughly 104% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !At about 931°C (1707°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
  • Surface gravity is close to Earth's, at least 1.12 times, so you would move much as you do here.
  • !Its star delivers about 341 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Earth-similarity index 0.18: this world has almost nothing in common with our own.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

Common questions

What is the gravity on DMPP-6 b?

DMPP-6 b's surface gravity is at least 1.1 times Earth's, and possibly more: its mass is only a lower bound.

How much would you weigh on DMPP-6 b?

Someone who weighs 150 pounds on Earth would weigh at least 167 pounds on DMPP-6 b.

How far is DMPP-6 b from Earth?

DMPP-6 b lies about 178 light-years from Earth.

How long would it take to get to DMPP-6 b?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 277,891 years.

How hot is DMPP-6 b?

DMPP-6 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 931°C (1707°F).

How long is a year on DMPP-6 b?

DMPP-6 b completes one orbit of its star in 7.6 days.
