TOI-3053 b
A confirmed world orbiting TOI-3053, 1,101.2 light-years away.
A gas giant
13.56 Earth radii, Jupiter-class (Jupiter is 11.2). At only 270.2 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky. Orbiting this close, it is a classic 'hot Jupiter', a giant that migrated inward from where it formed.
The orbit
Its year, one full orbit, takes just 3.0 Earth days.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 1,017 °C. Hot enough to melt copper; any surface would glow. It receives 460.0 times the starlight Earth gets.
Its sun
Its star is Sun-like (5,378 K, G8-K0 V; the Sun is 5,772 K).
How far is that, really?
At 1,101 light-years, tonight's light from this system left it around the year 924. A Voyager-speed probe would need roughly 19,482,941 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 2026 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.
