Mercury is the planet in our solar system that orbits the sun at an average speed of about 170,500 kilometers per hour (at its fastest point).
Mercury travels the fastest among the eight planets in our solar system. It orbits the Sun at an average speed of about 47.87 kilometers per second.
In space, an object will continue to move at a constant speed unless acted upon by an external force. This is known as Newton's first law of motion. Therefore, if you were to travel in space unaided, you would continue moving at a constant speed without slowing down.
The length of day and night on a planet depends on its rotational period, which is the time it takes for the planet to complete one full rotation on its axis. Planets with faster rotations have shorter days and nights, while planets with slower rotations have longer days and nights. Factors such as the planet's size, distance from the sun, and axial tilt also play a role in determining day and night lengths.
Of coarse the space shuttle begins launch at zero miles per hour but after about 8 seconds it is going about 100 mph (161 kph) 17 seconds into the launch it's going about 341 mph (549 kph)! Within 10 minutes it will be in orbit traveling about 17,500 mph (28,164 kph).
