Useless to you, because you aren't interested in scientific accuracy.
NMS planets aren't planets. They are not inside a star system. They are little colourful balls.
Elite planets have gravity. They are actually moving through space on the correct orbit. Their colour is based on the material composition which is based on the star type. They have a correct day and night cycle. They have the size of real planets. The terrain is based on tectonic plates. Craters are placed at positions which would be exposed to asteroid impacts. I could go on.

You just can't compare them.
Now that is the biggest load of garbage I've read here in awhile, sorry, but it is.
Gravity. Its a kind of gravity which doesn't work correctly. It is estimated by some math. It adds absolutely nothing to a 'sim' or indeed the game. A simple truth is, if the 'gravity' actually worked, I'd need to use delta-v and a whole lot of other calculations to get me off the planet. In Elite I point upwards and press go.
The colour is based on the start type. Well yippee do. If star == neutron set colour = blue. Yay it's a sim !
They have a correct day and night cycle. Eh, no they don't. How come one side is always darK and when you get closer it brighten up? Is by ship a sun ?
They have size of real planets. Says who? What you mean is they look big.
The Terrain is based on tectonic plates. Nope. How could they possible know the makeup of all these planets and their internal structures, plate density, plate mass etc? If you believe that you are just gullible.
Craters are placed at positions... blah blah. Were you drinking heavily or something when you posted this? Any place on a planet has an equal chance of being hit by an asteroid, unless, you want to get into quantum math and we'll start mapping every asteroid, it's lunar cycles, velocity, delta-v, density and it's chance of hitting every single planet in the known universe.
Elite Universe, while based on simple science is nothing more than guess work programmed into a generator. For sure NMS doesn't do any of that. But tell me this; When you sit down with your mates, do you tell them all about the gravitational science in Elite or do you just say you were 'playing' Elite.
How is it, if I leave my ship at 0 speed above a planet it does not get sucked down to the surface? I mean, with all your Gravity, surely... That would happen? How can I fly to the surface, but only land by using my down thrusters? Why doesn't my ship just fall to the surface?
How is it, with all these scientifically places craters, we cannot gather materials close to them other than the randomly generated materials placed at random distance apart?
Elite is just coloured balls too. Get over it.
