Size It Up answer: September 6

The five Mixed silhouettes for September 6, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 3 ran from a basketball (24 cm) to Earth (12,740 km). The widest gap was round 5, Ceres against Earth, at 14×; the closest call was round 1, Mercury against Pluto, only 2.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Mercury vs Pluto

    Pluto · reference · 2,376 km
    Mercury · true diameter · 4,879 km

    2.1× wider than Pluto

    Mercury is about 4,879 km across.

  2. ROUND 2

    Basketball vs Moose (Bull)

    Moose · reference · 2.7 m
    Basketball · true diameter · 24 cm

    11× shorter than the moose

    A basketball is about 24 cm across.

  3. ROUND 3

    Sperm Whale (Male) vs Holstein Cow

    Holstein Cow · reference · 2.5 m
    Sperm Whale · true length · 16 m

    6.4× longer than the Holstein cow

    A bull sperm whale runs about 16 m, a third of that being head.

  4. ROUND 4

    Orca vs Polar Bear (Male)

    Polar Bear · reference · 2.4 m
    Orca · true length · 7 m

    2.9× longer than the polar bear

    An orca is about 7 m long — a dolphin the size of a minibus.

  5. ROUND 5

    Ceres vs Earth

    Earth · reference · 12,740 km
    Ceres · true diameter · 940 km

    14× shorter than Earth
