If it is visible with the naked eye, why did it take so long to find?
Quoting: BadMoonRising 4583236 Like Astromut said, the planet's not visible (No planet is, because they're too small and way too dim.) We find these by measuring the tug the planet has on it's star as it orbits. We're just getting better at this, and are launching satalites to measure more accurately how the stars are affected.
