Today's five space Size It Up comparisons with the measured size of each object, its reference and a source you can check. The puzzle is still live, so every answer stays hidden until you tap it. Haven't played yet? Play today's puzzle first.
The November 7, 2026 puzzle ran from the Hubble Space Telescope at 13.1 m to Jupiter at 139,820 km — 7 orders of magnitude apart, drawing on space. The pair furthest apart was round 2: Mars is about 1.9× smaller than Earth.
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: Mars — 6,779 km. Mars measures 6,779 km (length / span), which is about 1.9× smaller than the reference, Earth at 12,742 km.
Mars is a little over half Earth’s diameter.
Common miss: players tend to inflate Mars when it sits beside Earth — big things get squeezed, small familiar things get stretched.
Answer: Jupiter — 139,820 km. 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: Hubble Space Telescope — 13.1 m. The Hubble Space Telescope measures 13.1 m (length / span), which is 1.2× as big as the reference, an American school bus at 10.7 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 an American school bus — 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 1.1× as big as the reference, an Argentinosaurus at 33 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 an Argentinosaurus — big things get squeezed, small familiar things get stretched.
