I watched Jeff bezos’s tour of blue origin facility with everyday astronaut.

He gave the reasoning for why New Glen has more than three legs (I think 6)

He said that the more legs you have, the smaller each leg has to reach out to give the same probability of tipping over. So there’s a formula to pick the best number of legs given their weight etc.

Interestingly he said they picked their number not just for that but also because it went well with the engine distribution.
