Episode notes
Why We're Seeing More Interstellar Objects
- New wide-field survey telescopes and better computers explain the recent rise in detected interstellar objects.
- Rubin and Pan-STARRS now routinely spot football-field-sized near-Earth objects previously unseen.
Speed Reveals Interstellar Origin
- Objects moving faster than ~42 km/s near Earth are unbound to the Sun and thus interstellar.
- Oumuamua and subsequent finds showed these high-speed signatures indicate extrasolar origin.
Size Scales: Regional Versus Global Risk
- A football-field object would cause severe regional devastation but not global catastrophe.
- The dinosaur-killer was roughly Manhattan-sized and would trigger planetary-scale effects.
