Confirmed exoplanet · Database record + computed analysis
HIP 94235 b
A confirmed world orbiting HIP 94235, 190.8 light-years away.
A sub-Neptune
3.00 Earth radii, likely a rocky core under a thick gas or steam envelope rather than a walkable surface. With 379.0 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year, one full orbit, takes just 7.7 Earth days. The orbit is strongly stretched (eccentricity 0.32), so its distance from the star, and with it the climate, swings dramatically.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 787 °C. Hotter than Venus's surface. It receives 219.3 times the starlight Earth gets.
Its sun
Its star is Sun-like (5,991 K, G V; the Sun is 5,772 K). The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 191 light-years, tonight's light from this system left it around the year 1835. A Voyager-speed probe would need roughly 3,376,615 years to get there.
How we found it
It was found by the transit method: the planet crosses its star's face on schedule, dimming it by a tiny, repeating fraction. The dip's depth gives the planet's size. The discovery was announced in 2022 from Transiting Exoplanet Survey Satellite (TESS).
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.
