To orbit the Earth, a speed of 7.9 kilometers/second is required. To escape Earth's gravity, an initial speed of 11.2 kilometers/second is required. To travel to distant planets, the initial speed must be still higher.
The speed of a spacecraft can vary depending on its mission and stage of flight. During launch, spacecraft can reach speeds of around 25,000 mph (40,000 km/h) to break free of Earth's gravity. In orbit, spacecraft can travel at speeds of around 17,500 mph (28,000 km/h) to maintain stable orbits.
The maximum speed reached by a manned spacecraft was during the Apollo 10 mission in 1969, when the spacecraft reached a speed of about 24,791 mph (39,897 km/h) relative to Earth. This speed was necessary to escape Earth's gravity and travel to the Moon.
The speed of a spacecraft can be measured by tracking its position over time using instruments such as radar or GPS. The velocity of the spacecraft can then be calculated by determining the rate at which its position is changing. Additionally, spacecraft may use onboard sensors like accelerometers to measure speed and acceleration.
The maximum speed of the Apollo 13 spacecraft during its journey to the Moon was approximately 24,790 miles per hour.
A person will travel at the same speed as the spacecraft from which they have exited since they are no longer being propelled by any additional force. Their speed would be determined by the velocity of the spacecraft at the moment of exit.
It takes around 3 days for a spacecraft to travel from Earth to the moon. This time can vary depending on the exact trajectory and speed of the spacecraft.

it depends on the craft
The maximum speed of the Apollo 13 spacecraft during its journey to the Moon was approximately 24,790 miles per hour.
It stabilizes or de-stabilizes it. A spacecraft needs to maintain a relative velocity of 25,000 miles per hour in order to counteract the earth's gravitational pull on the spacecraft. At a lesser speed, the craft will start to fall back to earth.
A person will travel at the same speed as the spacecraft from which they have exited since they are no longer being propelled by any additional force. Their speed would be determined by the velocity of the spacecraft at the moment of exit.
It takes around 3 days for a spacecraft to travel from Earth to the moon. This time can vary depending on the exact trajectory and speed of the spacecraft.
Speed on spacecraft is typically measured using instruments that track the craft's velocity relative to its starting point or to another reference point in space. This can be calculated using onboard sensors, such as accelerometers or radar systems, that measure the spacecraft's distance traveled over time. Speed can also be determined by tracking the Doppler shift in radio signals between the spacecraft and ground stations.
the speed of a comet and the rotation is far too fast for a spacecraft to land
That refers to using the gravity of a planet - for example Jupiter - to speed up a spacecraft. Note that the spacecraft approaches the planet with a certain speed, and goes away from it at the same speed, with respect to the planet. However, since in doing so it changes direction, and since the planet orbits the Sun, it is possible to set things up so that the spacecraft leaves with a greater speed with respect to the Sun.
Apollo 10 set the record for the fastest manned vehicle during the return trip from the moon on 26 May, 1969 ( they did not land, only rehearsed some of the descent techniques). The spacecraft reached a speed of 39,897 km/h (24,791 mph).
