How it was found
First planet found in 2024, by radial velocity and transit (NASA Exoplanet Archive).
Its planets
TIC 139270665 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 3 Earth years; about −73 °C, below freezing; found in 2024 by radial velocity.
TIC 139270665 b — 7.2 times Earth's width, Neptune-sized; its year lasts 24 days; about 430 °C, hotter than boiling water; found in 2024 by transit.
