5/9 At roughly 10 kilometres across, A11pl3Z would be the largest of the three known interstellar visitors.

Currently beyond Mars's orbit, it's heading inward but poses no danger to Earth—it won't get closer than Mars's distance.

4/10 Impact odds by asteroid size:

• 10m diameter: Once per decade (window-breaking)
• 140m diameter: Once every 1,000 years (devastating)
• 1km diameter: Once every 700,000 years (civilisation-ending)

Bigger = rarer, thankfully.
