Synthetic Euclid: one million systems

The same statistics as the catalogue, computed on one million systems that nobody has visited: predicted by the Oracle from their address alone, on regions drawn at random across the whole galaxy.

Systems predicted
1 000 000
1 799 regions drawn uniformly over Euclid
Bodies per system 4.76 planets and moons on average, at most 6
Systems per region 597 median, from 275 to 685, mean 556
Regions sampled 1 799 drawn at random
