    Mercury has an orbital speed of 47.4 km/s (29.5 mi/s), whereas Earth's orbital speed is 29.8 km/s (18.5 mi/s). Therefore, the spacecraft must make a larger change in velocity to get to Mercury and then enter orbit, as compared to the delta-v required for, say, Mars planetary missions.

    Few missions have targeted Mercury because it is very difficult to obtain a satellite orbit around the planet. Mercury orbits the Sun very quickly (between 24.25 miles per second (39.03 km/s) and 30 miles per second (48 km/s)), so spacecraft must be travelling very fast to reach it.

    Orbit and Rotation. Mercury's highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles (47 million kilometers) and as far as 43 million miles (70 million kilometers) from the Sun. It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, faster than any other planet.
