Size It Up Space answer: October 29
The five Space silhouettes for October 29, 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 56 ran from Mimas (396.4 km) to the Sun (1,391,000 km). The widest gap was round 4, Sun against GJ 1132, at 4.5×; the closest call was round 2, Kepler-186 f against TOI-700 e, only 1.3× 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 Oberon (Uranus’s moon · mean diameter)
Oberon · reference · 1,523 km Mimas · true diameter · 396.4 km 3.8× shorter than Oberon
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
Kepler-186 f (estimated planetary diameter) vs TOI-700 e (estimated planetary diameter)
TOI-700 e · reference · 11,720 km Kepler-186 f · true diameter · 14,920 km 1.3× wider than TOI-700 e
Kepler-186 f has an estimated planetary diameter of about 14,924.8 km. This is the body’s size, not an orbital distance.
-
ROUND 3
WASP-39 b (estimated planetary diameter) vs WASP-12 b (estimated planetary diameter)
WASP-12 b · reference · 281,000 km WASP-39 b · true diameter · 182,900 km 1.5× shorter than WASP-12 b
WASP-39 b has an estimated planetary diameter of about 182,876.9 km. This is the body’s size, not an orbital distance.
-
ROUND 4
Sun (nominal diameter) vs GJ 1132 (estimated stellar diameter)
GJ 1132 · reference · 307,600 km Sun · true diameter · 1,391,000 km 4.5× wider than GJ 1132
Sun has a nominal photospheric diameter of about 1,391,400 km. This is the body’s size, not an orbital distance.
-
ROUND 5
TRAPPIST-1 f (estimated planetary diameter) vs Ganymede (Jupiter’s moon · mean diameter)
Ganymede · reference · 5,262 km TRAPPIST-1 f · true diameter · 13,330 km 2.5× wider than Ganymede
TRAPPIST-1 f has an estimated planetary diameter of about 13,330.2 km. This is the body’s size, not an orbital distance.
