ok so i calculated myself the gravity of the planets after an updated article of the planets's mass and here my results:
planet b= 0.679g
planet c= 1.463g
planet d= 0.554g
planet e= 0.713g
planet f= 0.33g
planet g= 0.446g
planet h= 0.167g
for planet e i used an average of 0.56xEarth mass
it seems in your addon you used other value that changed the g alot (our two results...) but i am probably the one who got it wrong
so it seems planet g Is not a gas planet after all? very lower g than first results expacted...
took my half an hour to calculate all of that but it was good exercise for my mind
