Size It Up Space answer: November 1
The five Space silhouettes for November 1, 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 59 ran from Janus (178.4 km) to HD 189733 b (161,600 km). The widest gap was round 2, HAT-P-11 b against TRAPPIST-1 g, at 3.9×; the closest call was round 1, Janus against Phoebe, 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
Janus (Saturn’s moon · mean diameter) vs Phoebe (Saturn’s moon · mean diameter)
Phoebe · reference · 213 km Janus · true diameter · 178.4 km 1.2× shorter than Phoebe
Janus, a moon of Saturn, has a mean diameter of about 178.4 km. This is the body’s size, not an orbital distance.
-
ROUND 2
HAT-P-11 b (estimated planetary diameter) vs TRAPPIST-1 g (estimated planetary diameter)
TRAPPIST-1 g · reference · 14,400 km HAT-P-11 b · true diameter · 55,620 km 3.9× wider than TRAPPIST-1 g
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 3
HD 189733 b (estimated planetary diameter) vs Saturn (mean diameter · globe only)
Saturn · reference · 116,500 km HD 189733 b · true diameter · 161,600 km 1.4× wider than Saturn
HD 189733 b has an estimated planetary diameter of about 161,572.2 km. This is the body’s size, not an orbital distance.
-
ROUND 4
Charon (Pluto’s moon · mean diameter) vs Triton (Neptune’s moon · mean diameter)
Triton · reference · 2,705 km Charon · true diameter · 1,212 km 2.2× shorter than Triton
Charon, a moon of Pluto, has a mean diameter of about 1,212 km. This is the body’s size, not an orbital distance.
-
ROUND 5
TRAPPIST-1 h (estimated planetary diameter) vs TRAPPIST-1 c (estimated planetary diameter)
TRAPPIST-1 c · reference · 13,990 km TRAPPIST-1 h · true diameter · 9,631 km 1.5× shorter than TRAPPIST-1 c
TRAPPIST-1 h has an estimated planetary diameter of about 9,630.9 km. This is the body’s size, not an orbital distance.
