Earth's orbital speed averages about 30 km/s (108,000 km/h; 67,000 mph), which is fast enough to cover the planet's diameter in seven minutes and the distance to the Moon in four hours.
That's the speed the planet is moving through space in its orbit about the sun. Earth's speed varies â¦ a bit because its orbit is slightly eccentric, but that's why we say mean orbital velocity. One can calculate this value by knowing two facts: 1. The earth is approximately 150 million km from the sun (mean distance) and travels approximately in a circular orbit 2.
