Explore NASA's Near-Earth Object (NEO) feed to learn which asteroids and comets are making close approaches to Earth. Choose a 7-day window, fetch the latest data, and view detailed approach metrics to plan observations or satisfy your curiosity.
NASA's NEO feed supports up to seven days at a time. The request uses the API key configured for this app (DEMO_KEY with shared rate limits).
Select a date range and fetch data to see near-Earth objects. NASA updates the feed multiple times per day, so check back often for new discoveries.
Close approach date is listed in UTC and indicates when the object passes the specified orbiting body. Convert to your local timezone for observation planning.
Miss distance shows how far the object will pass from the body in kilometers. Even small numbers represent vast distances — the Moon is roughly 384,400 km away from Earth.
Potentially hazardous objects meet NASA's size and approach criteria for closer monitoring. It does not mean an impact is imminent, only that scientists watch them carefully.
Estimated diameter is based on the object's brightness and may change as NASA refines observations. Review both minimum and maximum values for context.
