Confirmed exoplanet · Database record + computed analysis
TIC 172900988 b
A confirmed world orbiting TIC 172900988 Aa, 818.5 light-years away.
A gas giant
11.25 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year takes 200 Earth days (0.5 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 88 °C. It receives 5.8 times the starlight Earth gets.
Its sun
Its star is hotter than the Sun (6,050 K, F9), burning brighter and faster. The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 819 light-years, tonight's light from this system left it around the year 1207. A Voyager-speed probe would need roughly 14,481,546 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 2021 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.
