On the other hand -> thousands of satellites do orbit earth. Are they permanent? yes, some are as permanent as the moon. Are they as big? No. But define big ENOUGH.

The first is still a moon, doesn't matter if it is slowly moving away.
The second (satellites) are not moons if they are man made and/or too small. Not sure how big it has to be to be a moon, but it's probably something like a few miles in diameter.
