Confirmed exoplanet · Database record + computed analysis
TOI-1670 c
A confirmed world orbiting TOI-1670, 548.2 light-years away.
A gas giant
11.06 Earth radii, Jupiter-class (Jupiter is 11.2). At only 200.2 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
The orbit
Its year, one full orbit, takes just 40.7 Earth days.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 411 °C. Hotter than Venus's surface. It receives 14.6 times the starlight Earth gets.
Its sun
Its star is hotter than the Sun (6,170 K, F7 V), burning brighter and faster. It shares the system with 1 other known planet.
How far is that, really?
At 548 light-years, tonight's light from this system left it around the year 1477. A Voyager-speed probe would need roughly 9,698,393 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 2022 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.
