Sizekin Celestial bodies answer: October 28
The five Celestial bodies silhouettes for October 28, 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 4 ran from Pluto (2,376 km) to Saturn (273,600 km). The widest gap was round 2, Neptune against Venus, at 4.1×; the closest call was round 4, Pluto against Mercury, only 2.1× apart — the kind of round that separates a 90 from a 60.
ROUND 1
Saturn (with rings) vs Saturn (mean diameter · globe only)
Saturn · reference · 116,500 km Saturn · true diameter · 273,600 km 2.3× longer than Saturn
Saturn measures about 273,550 km across its main rings.
ROUND 2
Neptune (equatorial diameter) vs Venus (mean diameter)
Venus · reference · 12,100 km Neptune · true diameter · 49,530 km 4.1× longer than Venus
Neptune measures about 49,528 km across its equator, excluding rings.
ROUND 3
Jupiter (mean diameter) vs Neptune (mean diameter)
Neptune · reference · 49,240 km Jupiter · true diameter · 139,800 km 2.8× longer than Neptune
Jupiter has a mean diameter of about 139,822 km. This is the body’s size, not an orbital distance.
ROUND 4
Pluto vs Mercury
Mercury · reference · 4,879 km Pluto · true diameter · 2,376 km 2.1× shorter than Mercury
Pluto is about 2,376 km across — smaller than Russia is wide.
ROUND 5
Uranus (mean diameter) vs Jupiter
Jupiter · reference · 143,000 km Uranus · true diameter · 50,720 km 2.8× shorter than Jupiter
Uranus has a mean diameter of about 50,724 km. This is the body’s size, not an orbital distance.
