Well, I don’t know nearly as many people as you all do.
Prolly the best way to estimate their mass is move them all to the same spot and see how much it causes the earth to wobble.
If they’re too many, we’ll change the orbit and go crashing into ol’ Sol, which is exactly what happened to Krypton’s sun so maybe letting me handle it is not the best plan.
Or we could move them all to Guam and see if the island tips over...
