An unmanned spacecraft can reach the Moon a lot faster.
The fastest time was set by Nasa's New Horizons spacecraft, where it only took eight hours and thirty five minutes for it to travel to the Moon.
A fuel efficient European Space Agency (ESA) spacecraft called SMART 1 took 13.5 months to get there in 2003.
It takes around three days on average for a manned spacecraft to reach the Moon.
This is based on the nine manned missions to the Moon and the six which landed on its surface.
The exact average time for all these missions was about three days and six hours.
The time it takes does depend on several factors, including where the Moon is in orbit, the size of the spacecraft and the fuel it uses.
Today is the first US lunar landing attempt since the Apollo era, with an unmanned spacecraft scheduled to touch down on the moon.
At approximately 5:50 pm ET, the mission, which was created by NASA and Houston-based Intuitive Machines, is scheduled to land the Odysseus spacecraft, also known as "Odie," close to the lunar south pole.
