Kepler-1319 b
A confirmed world orbiting Kepler-1319, 338.9 light-years away.
A super-Earth
1.34 Earth radii. Worlds between Earth and Neptune in size are the most common in the galaxy, yet our Solar System has none, which is why each one matters. With 2.4 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year, one full orbit, takes just 2.9 Earth days. The orbit is strongly stretched (eccentricity 0.33), so its distance from the star, and with it the climate, swings dramatically. Orbiting this tightly around a cool star, it is very likely tidally locked: one hemisphere in permanent day, the other in permanent night.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 284 °C. Above water's boiling point. It receives 38.5 times the starlight Earth gets.
Its sun
Its star is a red dwarf (3,655 K surface): 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 339 light-years, tonight's light from this system left it around the year 1687. A Voyager-speed probe would need roughly 5,996,584 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 2016 from Kepler.
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.
