The October 30, 2026 puzzle ran from a Space Shuttle orbiter at 37.3 m to Earth at 12,742 km — 5 orders of magnitude apart, drawing on space. The pair furthest apart was round 3: Earth is 2.9× as big as Brazil.
Answer: The Moon — 3,474.8 km. The Moon measures 3,474.8 km (length / span), which is about 1.2× smaller than the reference, Australia at 4,000 km.
The Moon’s mean diameter is about 3,475 kilometres.
Common miss: players tend to inflate the Moon when it sits beside Australia — big things get squeezed, small familiar things get stretched.
Answer: Mars — 6,779 km. Mars measures 6,779 km (length / span), which is 2× as big as the reference, the Moon at 3,474.8 km.
Mars is a little over half Earth’s diameter.
Common miss: players tend to compress Mars when it sits beside the Moon — big things get squeezed, small familiar things get stretched.
Answer: Earth — 12,742 km. Earth measures 12,742 km (length / span), which is 2.9× as big as the reference, Brazil at 4,320 km.
Earth is about 12,742 kilometres across.
Common miss: players tend to compress Earth when it sits beside Brazil — big things get squeezed, small familiar things get stretched.
Answer: Saturn V Rocket — 110.6 m. A Saturn V rocket measures 110.6 m (height), which is 1.2× as big as the reference, the Statue of Liberty at 93 m.
Saturn V stood taller than the Statue of Liberty without its pedestal.
Common miss: players tend to compress a Saturn V rocket when it sits beside the Statue of Liberty — big things get squeezed, small familiar things get stretched.
Answer: Space Shuttle Orbiter — 37.3 m. A Space Shuttle orbiter measures 37.3 m (length / span), which is 1.7× as big as the reference, a Brachiosaurus at 22 m.
The orbiter alone is about as long as a short-haul airliner — the launch stack was far taller.
Common miss: players tend to compress a Space Shuttle orbiter when it sits beside a Brachiosaurus — big things get squeezed, small familiar things get stretched.
