How fast could the fastest rocket ship fly?

A:

NASA's Juno spacecraft is the fastest man made object ever recorded, at roughly 365,000 km/h (165,000 mph) as it approached Jupiter. The fastest launch velocity belongs to New Horizons, which went 58,000 km/h (36,000 mph). All these speeds are relative to Earth, as any object could be used as a reference for comparing speeds, especially in space. In 2018, the Solar Probe Plus, a NASA mission, is scheduled to fly into the Sun's atmosphere and reach a speed of 724,000 km/h (450,000 mph). If one were to travel at this speed, they could travel from the Earth to the moon in 30 minutes.
