Alright,
You may be thinking that there isn’t a difference between the 2 planets, being that Droo has exactly the same gravity as earth. Aside from continents, the radius of Droo I’ve calculated to be 1275km, whereas Earth’s is 6378km, roughly 5 times greater at the equator!
Knowing this, it would explain why the minimal orbital velocity is less than half of Earth’s, meaning all replica rockets with exact same stats do in fact perform unrealistically better than their real life counterparts. Hence intentionally reducing performance would help model some would-be rocket replicas a bit better, like the A10-A12 German launch platform.
Explained so beautiful n in detail that too just under 5 min..... Great work
