I just had a quiz where I learned that Earth has the largest density of all the planets in the solar system.
My thought was that density would directly correlate to the gravity of the planet, and the planet with lower jumping heights had higher gravitational pull because of a higher density. While not having any clear mental table of the gravity or jumping height for the different planets, I thought that you’d jump the shortest distance on Jupiter, and deduced that Jupiter therefore would have the heighest gravitational pull and the largest density. This was wrong. Probably on multiple levels. I tried searching google for ”planets gravity jumping density reddit” but didn’t find anything suitable for my attention span to understand the data and the concepts.
Therefore I’m turning to you. What are the flaws in my childish thinking? What are the relationships for mass/gravity/density/jumping distance, and do you know of any good table where these are shown for the different planets?

As another said the mass matters but density is also important since it influences the distance from. The surface to the center of the planet.
If earth was twice denser gravity would be stronger at the surface and it would also be harder to jump.
