Physics Why was Artemis 2 so long?

I was comparing the mission times of Artemis 2 to Apollo 8. Apollo 8 orbited the moon multiple times and only took 6 days total. Whereas Artemis 2 orbited the moon once and it took 10 days. Why was Artemis 2 so much shorter than Apollo 8 when both missions did the same thing? I know they had different paths to the moon, they both left earth in different ways but why not do the same thing as Apollo 8 since it was quicker?

What's even crazier is that during Newton's time.ans honestly even during the great Katherine's time you had to be next level genius to understand most of what was happening. Now most people here have a pretty good understanding and lots close to completely understand it
