Size It Up Space answer: October 8
The five Space silhouettes for October 8, 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 35 ran from Thebe (98.6 km) to Kepler-186 (727,700 km). The widest gap was round 2, TOI-700 against Jupiter, at 4.2×; the closest call was round 1, GJ 1214 against LHS 3844, 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
GJ 1214 (estimated stellar diameter) vs LHS 3844 (estimated stellar diameter)
LHS 3844 · reference · 263,000 km GJ 1214 · true diameter · 300,800 km 1.1× wider than LHS 3844
GJ 1214 has an estimated stellar diameter of about 300,820.7 km. This is the body’s size, not an orbital distance.
-
ROUND 2
TOI-700 (estimated stellar diameter) vs Jupiter (mean diameter)
Jupiter · reference · 139,800 km TOI-700 · true diameter · 585,800 km 4.2× wider than Jupiter
TOI-700 has an estimated stellar diameter of about 585,779.4 km. This is the body’s size, not an orbital distance.
-
ROUND 3
Mars (mean diameter) vs Ganymede (Jupiter’s moon · mean diameter)
Ganymede · reference · 5,262 km Mars · true diameter · 6,779 km 1.3× wider than Ganymede
Mars has a mean diameter of about 6,779 km. This is the body’s size, not an orbital distance.
-
ROUND 4
GJ 1132 (estimated stellar diameter) vs Kepler-186 (estimated stellar diameter)
Kepler-186 · reference · 727,700 km GJ 1132 · true diameter · 307,600 km 2.4× shorter than Kepler-186
GJ 1132 has an estimated stellar diameter of about 307,638.5 km. This is the body’s size, not an orbital distance.
-
ROUND 5
Amalthea (Jupiter’s moon · mean diameter) vs Thebe (Jupiter’s moon · mean diameter)
Thebe · reference · 98.6 km Amalthea · true diameter · 167 km 1.7× wider than Thebe
Amalthea, a moon of Jupiter, has a mean diameter of about 167 km. This is the body’s size, not an orbital distance.

Every round is worth up to 100 points: within 6% of the true size scores 100, half or double scores 45, five times off scores zero. The daily puzzle is the same five for everyone and refreshes at midnight in your time zone; if you want more than five, Size It Up Unlimited draws fresh pairs from the whole library for as long as you like.
