It is believed that the fasted speed with which any object can travel is the speed of light. So you can consider it to be the fastest speed at which we can travel in space which is 186,000 miles per second or 300,000 kilometers per second.
At present the maximum speed achieved by human made spacecraft is 39,000 km/h (more than 24,000 mph).
