Here's a breakdown:

* Apollo missions: The Apollo missions, which landed humans on the Moon, took about 3 days to reach the lunar surface.

* Modern spacecraft: Modern spacecraft, such as the Artemis missions, are designed to take a similar amount of time, around 3 days.

Factors affecting travel time:

* Launch velocity: The faster the spacecraft is launched, the shorter the travel time.

* Trajectory: The chosen trajectory, such as a direct or spiral path, can affect the duration.

* Mission objectives: The mission's objectives might influence the travel time, for example, a flyby mission might be faster than a lunar landing mission.

Note: The exact travel time can vary depending on these factors.
