ok I can explain, [REDACTED] Planets are anomaly planets with strange creatures and plants and sometimes high electromagnetic frequencies so that's good, but they usually aren't the best planets to live on. If you're looking for rare planets look for Pillared Planets, they have a 0.1% chance of spawning which is 1 in 1,000 planets scanned or found so yeah but really cool! (Yes I'm a no man's sky nerd)
