Size It Up Space answer: November 5
The five Space silhouettes for November 5, 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 63 ran from Pan (28 km) to HD 189733 (1,044,000 km). The widest gap was round 1, Pan against Epimetheus, at 4.2×; the closest call was round 2, Proxima Centauri against HD 189733 b, only 1.2× apart — the kind of round that separates a 90 from a 60.
SPOILER · TODAY’S FIVE
You have not finished today’s puzzle on this device. The answers below are blurred so you can still play first.
-
ROUND 1
Pan (Saturn’s moon · mean diameter) vs Epimetheus (Saturn’s moon · mean diameter)
Epimetheus · reference · 116.4 km Pan · true diameter · 28 km 4.2× shorter than Epimetheus
Pan, a moon of Saturn, has a mean diameter of about 28 km. This is the body’s size, not an orbital distance.
-
ROUND 2
Proxima Centauri (estimated stellar diameter) vs HD 189733 b (estimated planetary diameter)
HD 189733 b · reference · 161,600 km Proxima Centauri · true diameter · 196,200 km 1.2× wider than HD 189733 b
Proxima Centauri has an estimated stellar diameter of about 196,187.4 km. This is the body’s size, not an orbital distance.
-
ROUND 3
HAT-P-11 b (estimated planetary diameter) vs WASP-107 b (estimated planetary diameter)
WASP-107 b · reference · 133,700 km HAT-P-11 b · true diameter · 55,620 km 2.4× shorter than WASP-107 b
HAT-P-11 b has an estimated planetary diameter of about 55,617 km. This is the body’s size, not an orbital distance.
-
ROUND 4
HD 189733 (estimated stellar diameter) vs LHS 3844 (estimated stellar diameter)
LHS 3844 · reference · 263,000 km HD 189733 · true diameter · 1,044,000 km 4.0× wider than LHS 3844
HD 189733 has an estimated stellar diameter of about 1,043,550 km. This is the body’s size, not an orbital distance.
-
ROUND 5
Prometheus (Saturn’s moon · mean diameter) vs Metis (Jupiter’s moon · mean diameter)
Metis · reference · 43 km Prometheus · true diameter · 86.2 km 2.0× wider than Metis
Prometheus, a moon of Saturn, has a mean diameter of about 86.2 km. This is the body’s size, not an orbital distance.
