I would have thought the ratio of day and night would be about 50/50, but no - seems more like 90% night and 10% day...
You noticed that well, and unfortunately this applies not only to the day/night ratio, but also to almost all trips.
When you enter a star system and move towards something, be it a space station, planetary port, POI, signal source - in 90 - 95% of cases it will be behind your back, on the invisible side of the sky. On the planet, your destination will almost always be on the opposite side.
Not always - that would be naive - but in 90 to 95% of cases.
When I finish the fight after the interdiction, and my ship changes orientation 100 times during the fight, the station I just traveled to will be behind me. And so on.
In the real universe, when dealing with large numbers, that ratio would inevitably tend towards 50 - 50. But not in the ED universe. It always remains 90-10. That's how and how much ED is a simulation and how much FDev respects the player's time.
Someone could tell me that it is an insignificant time, you turn the ship in 10 seconds, you go around the planet in one minute - but I will repeat - when it comes to big numbers, it is no longer an insignificant time. And when it's applied to hundreds and thousands of players, it really is an unprecedented waste of time.
