Mostly, but it also depends on the density - a high mass but large and low density planet may have low surface (or "surface" in the case of gas giants) gravity. In game terms, metal rich planets have the highest density and the highest "gravity per mass" while the likes of icy planets have a comparatively low "gravity per mass" - a 4 Earth mass MRW will have much higher surface gravity than a 4 Earth mass Icy world.
Well yeah I only applied it to landable planets as the gas giants arent and I don't wanna try to land on neutron stars, white dwarfs or black holes..
and ice planets have ice which isn't the most densest thing..
(that's us pilots *snort*)
so the golden rules for elite explorers are:
1.Never fly without Rebuy
2. Never forget KGB-FOAM
3.Never fly without ADS and, if you value your dosh, not without DSS
4. Always check gravity of your planet before attempting a landing, it takes only a second as its right before your eyes on your hud when even lightly entering the planets zone.
If you want to use the neutron highway, bring two AFMU's
5.A heatsink in need is a friend indeed and also practical to speed up as it allows you to jump near hot stars or leave a planet when you ship needs a few second to get THAT YOU ARE AIMING AT THE RIGHT TRAJECTORY ALREADY GOSH DAMMIT
