Confirmed exoplanet · Database record + computed analysis
HD 196067 c
A confirmed world orbiting HD 196067, 130.2 light-years away.
A sub-Neptune
3.21 Earth radii, likely a rocky core under a thick gas or steam envelope rather than a walkable surface. At only 10.4 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
The orbit
Its year, one full orbit, takes just 4.6 Earth days.
Its sun
Its star is hotter than the Sun (6,072 K, G0 V), burning brighter and faster. The system holds 2 stars, so its skies have more than one sun. It shares the system with 1 other known planet.
How far is that, really?
At 130 light-years, tonight's light from this system left it around the year 1895. A Voyager-speed probe would need roughly 2,304,447 years to get there.
How we found it
It was found by the radial-velocity method: the planet's gravity swings its star in a small circle, and that wobble shows up as a rhythmic Doppler shift in the starlight. The wobble's size gives the planet's minimum mass. The discovery was announced in 2025 from La Silla Observatory.
Everything above is computed from the archive’s measured values for this planet. Where a quantity is missing, the statement is omitted rather than guessed.
About this record
The measured values come from the NASA Exoplanet Archive, and any missing value has not been determined yet; the Atlas never fills gaps with guesses. More standout worlds: Proxima b, TRAPPIST-1e, K2-18 b, 55 Cancri e, and the detection methods that found them all.
