Answer: 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: Earth measures 12,742 km (length / span), which is 1.9× as big as the reference, Mars at 6,779 km.
Earth is about 12,742 kilometres across.
Common miss: players tend to compress Earth when it sits beside Mars — big things get squeezed, small familiar things get stretched.
Answer: Saturn measures 116,460 km (length / span), which is about 1.2× smaller than the reference, Jupiter at 139,820 km.
Saturn is more than nine times wider than Earth.
Common miss: players tend to inflate Saturn when it sits beside Jupiter — big things get squeezed, small familiar things get stretched.
Answer: 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 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.
