Have you ever wondered how long it takes to travel to the Moon and return to Earth? This question pops up often, especially with space missions making headlines again.
While the Moon isn’t that far in space terms, the full round trip isn’t instant. In this short guide, you’ll learn how long the journey really takes and what affects the timing.
Distance Between Earth and the Moon
In space the moon is the closest celestial body to the earth, but it’s still pretty far away. On average, the moon sits about 384,400 kilometers (238,855 miles) from earth according to national Geographics. That’s roughly 30 earth sized planets stacked in a line.
But this distance doesn’t stay the same every day. The Moon moves in an oval shaped path called an elliptical orbit, so sometimes the moon becomes closer to the earth and sometimes it’s farther.
At the closest point the distance between moon and earth is about 363,300 km and at the farthest point the distance is about 405,500 km. When the moon is closest to the earth it is called perigee and at farthest point it’s called apogee.
This change in distance affects how long a trip from earth to moon can take.
Time It Takes to Travel to the Moon
The time it takes to reach the Moon depends on the type of mission and the speed of the spacecraft. For example, NASA’s Apollo 11 mission in 1969 took about 76 hours, just over 3 days to get there.
Modern spacecraft can sometimes make the trip faster but most crewed missions still follow a similar timeline. Some uncrewed probes, like NASA’s New Horizons, were much faster but weren’t designed to stop or land.
So, for a regular human mission, it usually takes 3 to 4 days to reach the Moon.
Return Journey from Moon to Earth
Coming back from the Moon usually takes about the same time as going roughly 3 days. But the return trip has its own challenges. Spacecraft must re-enter Earth’s atmosphere at very high speeds, around 40,000 km/h, which creates intense heat and pressure. Heat shields protect the crew during this stage. Once the spacecraft slows down, parachutes help it land safely in the ocean.
So, a full round trip to the Moon and back typically takes about 6 to 7 days, depending on the mission plan and re-entry path.

Final Thoughts: How Long Does It Take to Get to the Moon and Back to Earth?
So, how long does it take to get to the Moon and back to Earth? The short answer: around 6 to 7 days for a full round trip. Most crewed missions like Apollo 11, took about 3 days to reach the Moon and another 3 days to return.While modern spacecraft may be faster, human missions still follow careful timing for safety. So if you’re wondering about total travel time, expect it to be about 144 to 168 hours, it depends on speed and distance at launch.
