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.
What is the speed of Earth in its orbit in miles per hour? The Earth's orbit is an ellipse, so the speed varies a little; faster when the Earth is closer to the Sun (in January) and a little slower when the Earth is farther away ( in â¦July). But the difference is fairly small.
