Why it matters
- Kepler's very first planet candidate (KOI-1), only confirmed in 2019.
- Its 3.85-day orbit is shrinking by about 131 milliseconds per year.
- Will be consumed by its subgiant host in under 3 million years.
As of Nov 2025 the NASA Exoplanet Archive resolves the name but no longer lists it in its confirmed-planet tables; verify current status before publishing.
