Size It Up answer: September 18

The five Mixed silhouettes for September 18, 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 15 ran from a raccoon (68 cm) to Saturn (273,600 km). The widest gap was round 1, Siemens Vectron against Lion, at 9.0×; the closest call was round 4, Queen Mary 2 against Willis Tower, only 1.5× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Siemens Vectron vs Lion (Male)

    Lion · reference · 2.1 m
    Siemens Vectron · true length · 18.98 m

    9.0× longer than the lion

    The electric Vectron is 18.98 m over its buffers. The pantographs add height, not train length.

  2. ROUND 2

    Saturn (with rings) vs Jupiter

    Jupiter · reference · 143,000 km
    Saturn · true diameter · 273,600 km

    1.9× wider than Jupiter

    Saturn measures about 273,550 km across its main rings.

  3. ROUND 3

    Cessna 172 vs Bowhead Whale (adult female)

    Bowhead Whale · reference · 18 m
    Cessna 172 · true length · 8.3 m

    2.2× shorter than the bowhead whale

    A Cessna 172 is 8.3 m long — the most-produced aircraft in history.

  4. ROUND 4

    Queen Mary 2 vs Willis Tower (Sears Tower, to the tip)

    Willis Tower · reference · 527 m
    Queen Mary 2 · true length · 345 m

    1.5× shorter than the Willis Tower

    Queen Mary 2 is 345 m long — a whole ocean liner rather than one of its passenger decks.

  5. ROUND 5

    Polar Bear (Male) vs Raccoon (head to hindquarters)

    Raccoon · reference · 68 cm
    Polar Bear · true length · 2.4 m

    3.5× longer than the raccoon

    A male polar bear is about 2.4 m long.
