GJ 341 b
GJ 341 b is a confirmed rocky exoplanet 34.1 ly from Earth in the constellation Carina, discovered in 2025 by Transiting Exoplanet Survey Satellite (TESS).
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it (what that means).
Bathing the surface in deep orange light. A year passes in just 7.6 days, and at an estimated 356°C (673°F) it is blistering.
Catalog values (NASA Exoplanet Archive): mass 4.00 M⊕, radius 0.88 R⊕. Its catalog mass and radius imply a density of 32.3 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use GJ 341 b in gravity rankings or weight calculations.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 356°C (673°F), sound would travel roughly 48% 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.

How far is GJ 341 b from Earth?
GJ 341 b lies about 34.1 light-years from Earth.
How long would it take to get to GJ 341 b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 53,177 years.
How hot is GJ 341 b?
GJ 341 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 356°C (673°F).
How long is a year on GJ 341 b?
GJ 341 b completes one orbit of its star in 7.6 days.
