He's putting pieces back together/compressing them together, that's what we see in the comic. He doesn't have to do anything simultaneously, he just has to force a bunch of moon chunks back together into a moon shaped ball of moon. Chunks forced together by a scale of strength wayyy beyond the moon should stay together fine.
I'm going to have to ask for a scan from it showing that then because all I can find from that is J'onn ramming the moon and blowing it up in combination with Batman's moon killing bombs and the moon then blowing up as Vandal Savage and minions look up at the sky. It looks like huge chunks of moon blowing apart as he does.
edit: Are you saying the dots in space are moon dust? Because.. that's just how space is being drawn as far as any images of this thing I'm looking at. Space looked the exact same way while the moon was still intact and J'onn was talking about going for it. That's just a starscape.
And that aside? The moon is only so big on the scale of planets. There is only so much space he has to work in to assemble it, and there's only so intricate he has to go here. He's not assembling some complex thing of nuanced fine moving parts. He's shoving chunks of the moon back together and he's reaaalllly strong. Near light feels just fine as the basic minimum here.
