🪨 Static Electricity Is Critical to the Formation of Planets • Nautilus

「 "The dust particles need static electricity to make them “sticky” enough to cluster into pebbles that can form planets.

Only when particles grow larger than this threshold size—roughly a quarter of an inch, depending on conditions—can they eventually join to form rocky “planetesimals,” from about half a mile to 100 miles across 」
