TYC 3667-1280-1 b
A confirmed world orbiting TYC 3667-1280-1, 1,557.4 light-years away.
A gas giant
12.80 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year, one full orbit, takes just 26.5 Earth days.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 1,077 °C. Hot enough to melt copper; any surface would glow. It receives 544.0 times the starlight Earth gets.
Its sun
Its star is an orange K-type (5,130 K): cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 1,557 light-years, tonight's light from this system left it around the year 468. A Voyager-speed probe would need roughly 27,555,308 years to get there.
How we found it
It was found by the radial-velocity method: the planet's gravity swings its star in a small circle, and that wobble shows up as a rhythmic Doppler shift in the starlight. The wobble's size gives the planet's minimum mass. The discovery was announced in 2016 from McDonald Observatory.
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.
