2MASS J04414489+2301513 b
A confirmed world orbiting 2MASS J04414489+2301513, 392.8 light-years away.
A gas giant
12.60 Earth radii, Jupiter-class (Jupiter is 11.2). With 2383.6 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 -256 °C. Deep-freeze territory, colder than Antarctica's worst.
Its sun
Its star is a red dwarf (2,936 K surface), type M8.5: small, dim, flare-prone, and destined to outlive the Sun many times over.
How far is that, really?
At 393 light-years, tonight's light from this system left it around the year 1633. A Voyager-speed probe would need roughly 6,949,129 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 2010 from Hubble Space Telescope.
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.
