The October 25, 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 2: the Sun is 113227642× as big as a Tyrannosaurus rex.
Answer: International Space Station — 109 m. The International Space Station measures 109 m (length / span), which is 1.5× as big as the reference, a Boeing 747 at 70.7 m.
The ISS spans roughly 109 metres across its solar arrays.
Common miss: players tend to compress the International Space Station when it sits beside a Boeing 747 — 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 113227642× as big as the reference, a Tyrannosaurus rex at 12.3 m.
The Sun is about 1.39 million kilometres in diameter.
Common miss: players tend to compress the Sun when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Mars — 6,779 km. Mars measures 6,779 km (length / span), which is 1.5× as big as the reference, the contiguous United States at 4,500 km.
Mars is a little over half Earth’s diameter.
Common miss: players tend to compress Mars when it sits beside the contiguous United States — 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.
Answer: Perseverance Rover — 3 m. The Perseverance rover measures 3 m (length / span), which is about 1.5× smaller than the reference, a family sedan at 4.6 m.
Perseverance is about the length of a small car.
Common miss: players tend to inflate the Perseverance rover when it sits beside a family sedan — big things get squeezed, small familiar things get stretched.
