The average speed of the earth in orbit is around 30 km/sec or 108,000 km/h. The planet moves faster when it's closer to the sun and slower when it's further away, sweeping out equal areas in equal time.

How fast does the earth orbit the sun in kilometers a second?
60,000 miles per hour which multiplied by 1.5 kilometers in a mile comes to 90,000 kilometers per hour. ...
Asked in Science, Planetary Science, The Moon
How fast does moon travel in its orbit around the earth?
The moon travels in its orbit around the earth at a speed of 3,683 kilometers per hour. This is equal to 2,288 miles per hour and when it gets closer to the earth it moves the fastest. ...

How fast does the earth orbit the sun in kilometers per second?
About 30 km/second. It varies a bit; at periapsis, Earth moves somewhat faster than at apapsis. ...
Asked in Astronomy, Planet Mars, The Sun
Does the earth orbit twice as fast as mars?
Not quite exactly, or nowhere-near, depending on what you mean by "how fast". Period of orbit Earth . . . 365.26 earth-days Mars. . . . 686.97 earth-days The Earth takes 53.2% as long as Mars does to orbit the sun. But that's "orbiting about twice as frequently", not "orbiting twice as fast". Average orbital speed Earth . . . 29.8 kms-1 Mars. . . . 24.1 kms-1 Earth only moves 26% faster than Mars in its orbit. ...
Why does gravity hold moon with the earth?
Since the earth is larger than the moon it generates a more powerful magnetic field which pulls the moon towards the earth and causes it to orbit as the earth rotates on its axis, and the reason it stays in orbit is because the moon is moving fast enough to stay in orbit rather than be pulled into the earth yet it's not moving so fast that it will leave earths orbit. ...
