VHS J125601.92-125723.9 b
A confirmed world orbiting VHS J125601.92-125723.9, 41.4 light-years away.
A gas giant
13.67 Earth radii, Jupiter-class (Jupiter is 11.2). With 5085.3 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 5,800,000 Earth days (15879.5 Earth years). The orbit is strongly stretched (eccentricity 0.68), 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 921 °C. Hot enough to melt copper; any surface would glow.
Its sun
Its star is a red dwarf (2,620 K surface), type M7.5: 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 41 light-years, tonight's light from this system left it around the year 1984. That is close by galactic standards, which makes it a prime target for follow-up telescopes. A Voyager-speed probe would need roughly 732,860 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 2015 from Paranal 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.
