- Heads-up: asteroid 1997 NC1 will zip past Earth Saturday morning at about 1.6 million miles — completely safe.
- It's huge: roughly 0.75–1.65 km across, about the size of 2–4 Empire State Buildings.
- Skywatchers with binoculars or small telescopes might spot it; it won't come this close again until 2133.
