That's like calling a lifetime lived within just one village 'temporary'. On the scale of human events it's nearly as permanent as anything else for which we commonly ascribe permanence and reliability within lifetime scales.
It's fair to describe objects in relation to the lifespans of those objects, not of those who observe. "On the scale of human events" is not the only relevant timeframe for discussing celestial bodies.
