Kepler telescope s first detection is finally confirmed as a planet

摘要

A decade after being found, the first exoplanet candidate spotted by the Kepler space telescope has been confirmed as a real world.The planet orbits a star initially dubbed KOI 4, for Kepler Object of I nterest 4. When the planet passed in front of the star, it blocked a bit of starlight from reaching Kepler in Earth's orbit, alerting astronomers to the planet's existence.
