1997 NC1, a large near-Earth asteroid, is making a rare close pass by Earth. This object is estimated to be about 0.7–1.6 km wide, with a central estimate near 0.9 km, and it is listed as a Potentially Hazardous Asteroid (PHA) because of its size and orbit — not because it is expected to hit Earth.
In this video, I break down what 1997 NC1 is, how close it will come, why it is on the hazard list, and what the numbers actually mean. Its closest approach is expected on June 27, 2026, at roughly 2.6 million km from Earth — about 6.6 times the Earth–Moon distance. That is safely far away, but still close enough in astronomical terms to be watched carefully.
We will look at the flyby distance, relative speed, size estimate, orbit class, and why objects like this matter for planetary defense and backyard astronomy.
This is not an impact warning. It is a close-approach explainer using official asteroid tracking data and observational context.
Key points covered:
1997 NC1 — a ~1 km potentially hazardous asteroid
Closest approach June 27, 2026 (~2.6 million km / 6.6 lunar distances)
Why it's on the Potentially Hazardous list
Flyby distance, relative speed, and size estimate
How astronomers track near-Earth objects
