Size It Up Space answer: October 6
The five Space silhouettes for October 6, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 33 ran from Metis (43 km) to HD 209458 (1,656,000 km). The widest gap was round 1, Proteus against Epimetheus, at 3.6×; the closest call was round 5, HD 209458 against HD 189733, only 1.6× apart — the kind of round that separates a 90 from a 60.
