Size It Up Space answer: November 3
The five Space silhouettes for November 3, 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 61 ran from Amalthea (167 km) to HD 189733 (1,044,000 km). The widest gap was round 4, TRAPPIST-1 b against Moon, at 4.1×; the closest call was round 2, Proxima Centauri against WASP-12 b, only 1.4× 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
Mimas (Saturn’s moon · mean diameter) vs Amalthea (Jupiter’s moon · mean diameter)
Amalthea · reference · 167 km Mimas · true diameter · 396.4 km 2.4× wider than Amalthea
Mimas, a moon of Saturn, has a mean diameter of about 396.4 km. This is the body’s size, not an orbital distance.
-
ROUND 2
Proxima Centauri (estimated stellar diameter) vs WASP-12 b (estimated planetary diameter)
WASP-12 b · reference · 281,000 km Proxima Centauri · true diameter · 196,200 km 1.4× shorter than WASP-12 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
TRAPPIST-1 c (estimated planetary diameter) vs Kepler-22 b (estimated planetary diameter)
Kepler-22 b · reference · 26,790 km TRAPPIST-1 c · true diameter · 13,990 km 1.9× shorter than Kepler-22 b
TRAPPIST-1 c has an estimated planetary diameter of about 13,993.6 km. This is the body’s size, not an orbital distance.
-
ROUND 4
TRAPPIST-1 b (estimated planetary diameter) vs Moon (Earth’s moon · mean diameter)
Moon · reference · 3,475 km TRAPPIST-1 b · true diameter · 14,240 km 4.1× wider than the Moon
TRAPPIST-1 b has an estimated planetary diameter of about 14,235.9 km. This is the body’s size, not an orbital distance.
-
ROUND 5
LHS 1140 (estimated stellar diameter) vs HD 189733 (estimated stellar diameter)
HD 189733 · reference · 1,044,000 km LHS 1140 · true diameter · 300,400 km 3.5× shorter than HD 189733
LHS 1140 has an estimated stellar diameter of about 300,403.3 km. This is the body’s size, not an orbital distance.
