| Destination | Distance (km) | Cats Required | Stack Height |
|---|---|---|---|
| ISS Orbit | 408 | 887,826 | 408 km |
| The Moon | 384,400 | 835.6 million | 384,400 km |
| Sun (avg) | 150,000,000 | 326.1 billion | 150 million km |
| Mars (avg) | 225,000,000 | 489.1 billion | 225 million km |
The moon is far away—about 384,400 kilometers. A standard domestic cat is about 46 centimeters long. This calculator determines the number of cats you'd need to stack vertically to bridge the gap between Earth and its satellite.
While cats are known for their balance, a stack of this magnitude would be highly unstable. Additionally, the cats at the bottom would be quite unhappy, and the cats at the top would require tiny space suits.
Let's calculate Cat Tower for a typical scenario:
Distance: 384,400 km
Cat Length = 0.00046 km
384,400 / 0.00046 = 835,652,174 cats
Final Answer
835.6 Million Cats
If the stack falls, yes. But they'll be very confused about the lack of gravity.
The cats in the upper atmosphere will require pressurized suits and tiny helmets.
We recommend a very large quantity of catnip and laser pointers at the top.
This is a purely theoretical exercise. No cats were harmed in the making of this calculator.
