Size It Up Space answer: October 5
The five Space silhouettes for October 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 32 ran from Phoebe (213 km) to GJ 436 (633,100 km). The widest gap was round 1, Callisto against Pluto, at 2.0×; the closest call was round 5, GJ 436 against TOI-700, only 1.1× 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
Callisto (Jupiter’s moon · mean diameter) vs Pluto (mean diameter)
Pluto · reference · 2,377 km Callisto · true diameter · 4,821 km 2.0× wider than Pluto
Callisto, a moon of Jupiter, has a mean diameter of about 4,820.6 km. This is the body’s size, not an orbital distance.
-
ROUND 2
GJ 1132 (estimated stellar diameter) vs LHS 3844 (estimated stellar diameter)
LHS 3844 · reference · 263,000 km GJ 1132 · true diameter · 307,600 km 1.2× wider than LHS 3844
GJ 1132 has an estimated stellar diameter of about 307,638.5 km. This is the body’s size, not an orbital distance.
-
ROUND 3
K2-18 (estimated stellar diameter) vs GJ 1214 (estimated stellar diameter)
GJ 1214 · reference · 300,800 km K2-18 · true diameter · 571,900 km 1.9× wider than GJ 1214
K2-18 has an estimated stellar diameter of about 571,865.4 km. This is the body’s size, not an orbital distance.
-
ROUND 4
Phoebe (Saturn’s moon · mean diameter) vs Mimas (Saturn’s moon · mean diameter)
Mimas · reference · 396.4 km Phoebe · true diameter · 213 km 1.9× shorter than Mimas
Phoebe, a moon of Saturn, has a mean diameter of about 213 km. This is the body’s size, not an orbital distance.
-
ROUND 5
GJ 436 (estimated stellar diameter) vs TOI-700 (estimated stellar diameter)
TOI-700 · reference · 585,800 km GJ 436 · true diameter · 633,100 km 1.1× wider than TOI-700
GJ 436 has an estimated stellar diameter of about 633,087 km. This is the body’s size, not an orbital distance.
