It more or less reminds me of that Rick and Morty episode. They were playing an asteroid shooting.

At the end, I think there is little point in simulating the vastness of the universe in a video game (even just a fraction of it).
"I have never thought to myself that realism is fun" - Gabe NewellThere are levels to this. The NMS day/night cycle is geocentric.
It's a sandbox game yet when it comes to its "space" premise everything is thrown out the window. Dogfights carry no difficulty or skill. Flying around a system is pretty much pointless other than to stumble upon quests (100% RNG). Most of the fun you'll get at planet surface.
I don't think that simulating the vastness of the universe is ever going to be fun, but approximating a theme park ride that evokes the vastness of the universe can be breathtaking, like Outer Wilds was. (The gameplay is confined to a single solar system, but it certainly makes you feel both the a sense of adventure, and the vastness of space-time.)
