Gravitational parameter for planet-style gravity fields

[quartz gust]

In astrophysics, gravity gets stronger as you approach the center of a celestial body, and how much stronger it gets is determined by the distance to the celestial body, and the "standard gravitational parameter" of the celestial body (which is determined by a celestial body's mass and a fixed universal "gravitational constant" in real life). This means that if you're 200 meters away from the center of a black hole, and you move one meter closer, this results in a huge increase in gravity force, whereas getting a meter closer to the Moon from 200m away results in a relatively small change in gravity.

I'm unsure if this is the behavior in planet-style gravity fields as is, but if it isn't, it could be an interesting idea for the sake of allowing players to fine tune their planets' gravity and to allow for orbital mechanics, and for the sake of interesting and more freeing level design. Tweaking the gravitational parameter of a planet-style gravity fields could allow for huge gravity fields that don't change much as you approach or fly away from the planet (like the moon example), or tiny gravity fields that increase dramatically with the slightest of changes (like the black hole example).

Anyways, TL;DR i just wanna make orbital mechanics in Gelatinous Automobile: The Game

i'm brainstorming an idea where i force players to learn Hohmann transfers to efficiently get to and from a moon

indeed

My idea has this be entirely different from the normal gravity force multiplier

since I want to change the way the gradient between 0 gravity and max gravity goes

i love this idea

jellycars are soft bodies, so the uneven gravity from the two ends of the jellycar could result in orbit decay in most situations of this though
