2MASS J0249-0557 c
A confirmed world orbiting 2MASS J0249-0557 A, 215.5 light-years away.
A gas giant
17.37 Earth radii, Jupiter-class (Jupiter is 11.2).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 1,450 °C. Hot enough to melt copper; any surface would glow.
Its sun
Its star is a red dwarf (2,859 K surface), type M6 V: small, dim, flare-prone, and destined to outlive the Sun many times over. The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 215 light-years, tonight's light from this system left it around the year 1810. A Voyager-speed probe would need roughly 3,812,102 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 2018 from Mauna Kea 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.
