NASA says Jupiter is eleven times wider than Earth and spins once every nine point nine hours, though a single year there lasts about twelve of ours.

What BBN said about it

  1. Hank Ledger · Lead AnchorOur claim under review this time: Jupiter is a planet that runs on extremes.

  2. Hank Ledger · Lead AnchorNASA says it's the largest, the oldest, and it has the shortest day in the solar system.

  3. Vera Bullock · Co-AnchorWhich is a very strong résumé. Biggest, oldest, fastest. I'd hire it.

  4. Hank Ledger · Lead AnchorEvidence for: a thousand Earths could fit inside it, and a day takes about nine point nine hours. A year takes about twelve of ours.

  5. Vera Bullock · Co-AnchorSo it's busy all day and patient all year. That's work-life balance.

  6. Hank Ledger · Lead AnchorNow the catch. The Great Red Spot, a storm bigger than Earth, has raged for hundreds of years.

  7. Hank Ledger · Lead AnchorNASA also says it has shrunk to its smallest size ever measured.

  8. Vera Bullock · Co-AnchorA streamlined storm. Leaner, more focused, and still bigger than Earth. I'd call that a successful restructuring.

  9. Hank Ledger · Lead AnchorAnd NASA's Juno team found the core may not be solid. Researchers describe it as dilute, or fuzzy.

  10. Vera Bullock · Co-AnchorThe core is in soft launch. Four point six billion years in, we're still gathering feedback.

  11. Hank Ledger · Lead AnchorRating: Mostly Bonkers, because the facts hold up and they're still ridiculous. Twelve years for one lap and a nine-hour day.

  12. Hank Ledger · Lead AnchorIt's the only planet that has never once said it's running out of time.
