Hmm, I wonder which one is true?

Actually that isn't a problem. THat has to do with relativelity and time dilation. As a object's speed increases time will pass slower for that object relative to a "stationary" object. So, for instance, a trip to a star system 10 light years away at .75c would take something like 4 years 4 and a half months for the occupants, even though ten years would elapse on Earth. So if Alpha was travelling at a near light speed it would be able to go vast distances in months, while centures would pass for the rest of the universe.
THey even mention this a few times in the series too, and in the episode where they contact Earth, something like 20 years have passed, even though it has only been a couple of years on Alpha.
Plus the moon does go through a few stellar phenomena that shift it's position.
But, such speed causes some other problems for Alpha. One being that it would bee almost impossible for them to land an Eagle on a planet, and make it absolutely impossible for an Eagle that did land to make it back.
But then, this is Sci-Fi.
Still, they could have avoided all this if they has stuck with the original premise for the series.
