TIC 52059926 b
A confirmed world orbiting TIC 52059926, 706.4 light-years away.
A gas giant
10.71 Earth radii, Jupiter-class (Jupiter is 11.2). With 5380.0 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 176 Earth days (0.5 Earth years). The orbit is strongly stretched (eccentricity 0.51), 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 -44 °C. In the range where, with the right atmosphere, liquid water is conceivable; a real atmosphere could shift the true surface figure a lot (Earth's equilibrium value is −18 °C, yet we average +15 °C). It receives 4.5 times the starlight Earth gets.
Its sun
Its star is an orange K-type (4,505 K), K4.5 V: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 706 light-years, tonight's light from this system left it around the year 1319. A Voyager-speed probe would need roughly 12,497,919 years to get there.
How we found it
It was found by the transit method: the planet crosses its star's face on schedule, dimming it by a tiny, repeating fraction. The dip's depth gives the planet's size. The discovery was announced in 2026 from Transiting Exoplanet Survey Satellite (TESS).
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.
