The October 8, 2026 puzzle ran from the Perseverance rover at 3 m to the Sun at 1,392,700 km — 8 orders of magnitude apart, drawing on space. The pair furthest apart was round 4: the Sun is 19698727× as big as a Boeing 747.
Answer: Perseverance Rover — 3 m. The Perseverance rover measures 3 m (length / span), which is 1.3× as big as the reference, an adult horse at 2.4 m.
Perseverance is about the length of a small car.
Common miss: players tend to compress the Perseverance rover when it sits beside an adult horse — 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 about 1.9× smaller than the reference, a Boeing 747 at 70.7 m.
The orbiter alone is about as long as a short-haul airliner — the launch stack was far taller.
Common miss: players tend to inflate a Space Shuttle orbiter when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
Answer: Apollo Lunar Module — 6.9 m. The Apollo Lunar Module measures 6.9 m (height), which is 1.3× as big as the reference, an adult giraffe at 5.2 m.
It stood about as tall as a two-storey house, and only the top half ever came back.
Common miss: players tend to compress the Apollo Lunar Module when it sits beside an adult giraffe — big things get squeezed, small familiar things get stretched.
Answer: The Sun — 1,392,700 km. The Sun measures 1,392,700 km (length / span), which is 19698727× as big as the reference, a Boeing 747 at 70.7 m.
The Sun is about 1.39 million kilometres in diameter.
Common miss: players tend to compress the Sun when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
Answer: Starship Launch Stack — 121 m. A Starship launch stack measures 121 m (height), which is 1.1× as big as the reference, a Saturn V rocket at 110.6 m.
The complete Starship launch stack is about 121 metres tall.
Common miss: players tend to compress a Starship launch stack when it sits beside a Saturn V rocket — big things get squeezed, small familiar things get stretched.
