Notable Pass
Orbitfall Index

Asteroid 2018 LC1 is a near-Earth object catalogued by NASA under reference ID 3825100. Its estimated diameter is 28–62 m (average 45 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Mon, Jun 4, 2018, missing by 4,084,246 km — 10.62 lunar distances. NASA does not classify it as a potentially hazardous asteroid.

This score ranks how notable the asteroid approach is. It is not an impact prediction.
