Galactic year [ Trm Deskripshuhnz ]

Approximate orbit of the Sun (yellow circle) around the Galactic Centre. The galactic year…is the duration of time required for the Solar System to orbit once around the center of the Milky Way Galaxy. Estimates of the length of one orbit range from 225 to 250 million terrestrial years.

A galactic year is roughly the time it takes for the Solar System to make one complete revolution around the Milky Way Galaxy. That itself takes approximately 225 million Earth years.

The Earth is actually a fast-moving spacecraft. It orbits around Sun with an average speed of about 30 km/s (67,000 mph or 108,000 kmh), but what’s more, our galaxy, the Milky Way also rotates. It makes one rotation every 250 million years or so. As a result, our planet is approximately 18 galactic years old.
