      Two very different questions here I think 🙂

      Arthropods have muscles anchoring the joints of their exoskeletons. It’s actually quite similar to how we move except we have the decorum to keep our skeletons on the inside.

      Binary systems are pairs of celestial bodies that are so close together that they orbit a common centre point. We used to think that most stars are in binary systems, but we are not as certain as we once were.
