Answer: Jupiter measures 139,820 km (length / span), which is 1.2× as big as the reference, Saturn at 116,460 km.
Jupiter is almost eleven times wider than Earth.
Common miss: players tend to compress Jupiter when it sits beside Saturn — big things get squeezed, small familiar things get stretched.
Answer: the Hubble Space Telescope measures 13.1 m (length / span), which is 1.5× as big as the reference, a Triceratops at 9 m.
Hubble is roughly the size of a school bus, which is exactly what the Shuttle’s cargo bay was built to hold.
Common miss: players tend to compress the Hubble Space Telescope when it sits beside a Triceratops — 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 Sun measures 1,392,700 km (length / span), which is 18276902887× as big as the reference, a hockey puck at 7.6 cm.
The Sun is about 1.39 million kilometres in diameter.
Common miss: players tend to compress the Sun when it sits beside a hockey puck — big things get squeezed, small familiar things get stretched.
Answer: 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.
