Confirmed exoplanet · Database record + computed analysis
TOI-2373 b
A confirmed world orbiting TOI-2373, 1,659.1 light-years away.
A gas giant
10.42 Earth radii, Jupiter-class (Jupiter is 11.2). With 2955.8 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 13.3 Earth days.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 587 °C. Hotter than Venus's surface. It receives 69.9 times the starlight Earth gets.
Its sun
Its star is Sun-like (5,651 K; the Sun is 5,772 K).
How far is that, really?
At 1,659 light-years, tonight's light from this system left it around the year 366. A Voyager-speed probe would need roughly 29,353,989 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 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.
