What this report shows: Each day this page lists the 30 near-earth objects (NEOs) making the closest approach to Earth, ranked by miss distance. Data is pulled live from the NASA Near Earth Object Web Service (NeoWs) using the official NASA API. When fewer than thirty approaches occur on the current day, the list is filled from upcoming days within the next week.

Key terms: A Near Earth Object is an asteroid or comet whose orbit brings it within roughly 1.3 astronomical units of the Sun. A Potentially Hazardous Asteroid (PHA) is a NEO larger than about 140 meters that can pass within 0.05 AU of Earth. PHA status reflects long-term orbital characteristics, not an imminent threat.

Units used: km = kilometers, LD = lunar distances (1 LD is about 384,400 km), AU = astronomical units (1 AU is about 149.6 million km), km/s = kilometers per second, H = absolute magnitude.
