Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
How it was found
First planet found in 2026, by transit and transit timing variations (NASA Exoplanet Archive).
Its planets
TOI-5624 c — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 580 °C, hotter than boiling water; found in 2026 by transit.
TOI-5624 e — 3.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 21 days; about 340 °C, hotter than boiling water; found in 2026 by transit.
TOI-5624 f — 3.7 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 45 days; about 210 °C, hotter than boiling water; found in 2026 by transit timing variations.
TOI-5624 d — 3.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 14 days; about 440 °C, hotter than boiling water; found in 2026 by transit.
TOI-5624 b — 2.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 3 days; about 860 °C, hotter than boiling water; found in 2026 by transit.
