Confirmed exoplanet · Database record + computed analysis
TIC 139270665 b
A confirmed world orbiting TIC 139270665, 619.3 light-years away.
A Neptune-class world
7.23 Earth radii, in the ice-giant size range.
The orbit
Its year, one full orbit, takes just 23.6 Earth days.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 430 °C. Hotter than Venus's surface. It receives 40.3 times the starlight Earth gets.
Its sun
Its star is Sun-like (5,844 K, G2; the Sun is 5,772 K). It shares the system with 1 other known planet.
How far is that, really?
At 619 light-years, tonight's light from this system left it around the year 1406. A Voyager-speed probe would need roughly 10,956,835 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 2024 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.
