Answer
Astronomer Ole Rømer was a Danish scientist who made significant contributions to astronomy. He is best known for his discovery of the finite speed of light in 1676. Rømer's observations of the eclipses of Jupiter's moons led him to conclude that light takes time to travel, and he calculated its speed to be approximately 225,000 kilometers per second, which is close to the modern value of 299,792 kilometers per second.
