Yes. It was reported as a planet candidate in 2022, then confirmed in 2025 when the 5.12-day signal remained stable across NIRPS, HARPS, ESPRESSO, and archival measurements. NASA now lists it as a confirmed planet.

It orbits closer to the star than the classical habitable zone and receives about 1.8 times the stellar energy Earth receives. Its atmosphere and surface are unknown, so the catalog equilibrium temperature cannot establish real surface conditions.

The Proxima Centauri system is about 4.25 light-years from Earth, or roughly 40 trillion kilometres. Within that system, planet d orbits about 0.02881 AU—around 4.31 million kilometres—from its star.

One orbit takes 5.12338 Earth days. It is the innermost confirmed planet known around Proxima Centauri.

Its measured minimum mass is 0.260 ± 0.038 Earth masses, about twice Mars’s mass. NASA lists an estimated radius of 0.692 Earth radii, but there is no direct radius measurement, so its size and density remain uncertain.

Not as a resolved planet. It was detected through the extremely small Doppler wobble its gravity produces in the host star. The surface shown in this map is a scientific visualization, not an observation.

At light speed the journey would take about 4.25 years from Earth’s frame. At a speed comparable to Voyager 1, a direct trip would take roughly 75,000 years; no current spacecraft can make a practical interstellar journey.

Its very close, nearly circular five-day orbit makes synchronous rotation plausible, but its spin has not been directly measured. The map’s tidal-lock behavior is therefore a physical model, not an observed fact.
