Confirmed exoplanet · Database record + computed analysis
TWA 7 b
A confirmed world orbiting TWA 7, 110.9 light-years away.
A gas giant
12.70 Earth radii, Jupiter-class (Jupiter is 11.2). At only 108.1 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 43 °C.
Its sun
Its star is a red dwarf (3,509 K surface): small, dim, flare-prone, and destined to outlive the Sun many times over.
How far is that, really?
At 111 light-years, tonight's light from this system left it around the year 1915. A Voyager-speed probe would need roughly 1,961,745 years to get there.
How we found it
It was directly imaged, one of the rare planets actually photographed as its own point of light, possible only for young, hot, wide-orbiting giants. The discovery was announced in 2025 from James Webb Space Telescope (JWST).
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.
