HIP 38594 b

HIP 38594 b is a confirmed sub-Neptune exoplanet 58.0 ly from Earth in the constellation Puppis, discovered in 2020 by Multiple Observatories.

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

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 35°C (95°F), sound would travel close to its Earth speed, so your voice would sound much as it does on Earth. The real atmosphere is unknown.

The journey
Cosmic travel advisory
★★★★
Recommended, with reservations
  • Surface temperatures near 35°C (95°F) fall in the range where liquid water is at least possible.
  • Surface gravity is close to Earth's, at least 1.06 times, so you would move much as you do here.

Common questions

What is the gravity on HIP 38594 b?

HIP 38594 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 HIP 38594 b?

Someone who weighs 150 pounds on Earth would weigh at least 158 pounds on HIP 38594 b.

How far is HIP 38594 b from Earth?

HIP 38594 b lies about 58.0 light-years from Earth.

How long would it take to get to HIP 38594 b?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 90,486 years.

How hot is HIP 38594 b?

HIP 38594 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 35°C (95°F).

Is HIP 38594 b habitable?

HIP 38594 b orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.64. 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 HIP 38594 b?

HIP 38594 b completes one orbit of its star in 61 days.
