What this experiment does
Enter mileage so far and weekly habit. Optional age adds a calendar punchline for Moon arrival.
Uses an average Earth–Moon distance of 384,400 km.
How it works
Remaining km = max(0, 384,400 − lifetime km). Years = remaining ÷ (weekly km × 52).
Average lunar distance only. Orbit varies. Spacesuit, vacuum, and snack logistics are out of scope.
Frequently asked questions
Why 384,400 km?
It is a common round figure for the average Earth–Moon distance — an entertainment constant, not a navigation fix.
Do I need to enter age?
No. Age is optional and only used to estimate the calendar age when you arrive.
