Confirmed exoplanet · Database record + computed analysis
TIC 279401253 c
A confirmed world orbiting TIC 279401253, 931.4 light-years away.
A gas giant
12.60 Earth radii, Jupiter-class (Jupiter is 11.2). With 2549.0 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 155 Earth days (0.4 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 111 °C. Above water's boiling point. It receives 3.6 times the starlight Earth gets.
Its sun
Its star is Sun-like (5,951 K; the Sun is 5,772 K). It shares the system with 1 other known planet.
How far is that, really?
At 931 light-years, tonight's light from this system left it around the year 1094. A Voyager-speed probe would need roughly 16,479,773 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 2023 from Multiple Observatories.
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.
