How fast can a rocket go?
The speeds of rockets is normally measured in meters or kilometers per second (m/s, km/s or kps). Rockets have to go very fast to leave Earth and get into space. Here are a few examples of how fast rockets travel:
To get to low Earth orbit: 7.8 km/s (28,100 km/h; 17,400 mph).
To escape Earth's gravity and leave Earth behind: 11.19 km/s (40,284 km/h; 25,031 mph). This is known as Earth escape velocity.
Juno spacecraft heading to Jupiter: 58 km/s (209,000 kph; 130,000 mph). The speed is relative to the Sun.
Parker Solar Probe: 148 km/s (532,000 kph; 331,000 mph).
