# How Fast Can A Spaceship Travel?

## How fast could a spaceship travel?

That’s when the probe will reach its closest point to the sun, coming within 3.83 million miles (6 million kilometers) of our star. At that point, the spacecraft will be speeding along at a whopping 430,000 mph (692,000 km/h).

## What is the fastest spacecraft?

Parker Solar Probe Becomes Fastest-Ever Spacecraft. At about p.m. EDT, Parker Solar Probe surpassed 153,454 miles per hour — as calculated by the mission team — making it the fastest-ever human-made object relative to the Sun. This breaks the record set by the German-American Helios 2 mission in April 1976.

## How fast can the human body travel?

The gist of it is that the human body can withstand approximately 4 or 5 G (G = gravitational constant), an acceleration rate of approximately 40-50 m/s^2. To use a common measurement used in auto racing, that would be like going from 0 to 60 mph (0 to 100 km/h) in about 2/3 (4G) to 1/2 (5G) second.

## How fast can a rocket travel in space?

If a rocket is launched from the surface of the Earth, it needs to reach a speed of at least 7.9 kilometers per second (4.9 miles per second) in order to reach space. This speed of 7.9 kilometers per second is known as the orbital velocity, it corresponds to more than 20 times the speed of sound.
