CWISEP J193518.59-154620.3 b
A confirmed world orbiting CWISEP J193518.59-154620.3, 47.1 light-years away.
A gas giant
12.20 Earth radii, Jupiter-class (Jupiter is 11.2). With 4926.3 Earth masses packed into that size, its density points to rock and iron rather than gas.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 117 °C. Above water's boiling point.
How far is that, really?
At 47 light-years, tonight's light from this system left it around the year 1978. That is close by galactic standards, which makes it a prime target for follow-up telescopes. A Voyager-speed probe would need roughly 832,691 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.
