Near-Earth Asteroids
Which asteroids will pass Earth in the next 60 days: when, how far from us and from the Moon, how big they are and how fast they travel. NASA/JPL data, refreshed every three hours.

Distance scale: the next 14 days
Each dot is one close approach; dot size follows the estimated diameter. Hover or tap for details.
No approaches closer than 0.1 au are catalogued for the next two weeks.
Upcoming close approaches
—No approaches match the current filters. Clear them — a handful of small asteroids usually pass Earth every week.
Past week
—No approaches closer than 0.1 au were recorded over the past week.
How to read the close-approach list
A close approach is the moment an asteroid passes the point of its orbit nearest to Earth. This page lists every known object that will come within 0.1 astronomical units over the next 60 days — roughly 15 million kilometres, or about 39 times the distance to the Moon. To make the numbers intuitive, distances are given in lunar distances (LD, ≈ 384,400 km): a value below one means the asteroid passes closer than the Moon. The 0.05 au threshold (≈ 19.5 LD), combined with a size above 140 m, is what defines a "potentially hazardous asteroid" — although being on this list is not a threat in itself: the orbits of these bodies are known and computed decades ahead.
Most asteroids have never been measured directly — radar and infrared telescopes reach only a few of them. For the rest, the diameter is estimated from the absolute magnitude H, i.e. from how bright the object is: D = 1329 / √p · 10^(−H/5) kilometres, where p is the geometric albedo, the reflectivity of the surface. Like JPL, we assume an average albedo of 0.14, but real values range from about 0.05 (dark carbonaceous bodies) to 0.4 (bright stony ones), so the true diameter can differ from the estimate by a factor of 1.5–2 either way. Where a diameter has been measured, the row says "measured"; otherwise it says "estimated from H". The size classes (tiny, bus-sized, building-sized, large) are only there to help intuition.
The data comes from the NASA/JPL Small-Body Database close-approach API (Center for Near-Earth Object Studies). JPL recomputes orbits daily as new observations arrive, so the distance and time of a recently discovered object can shift noticeably from one day to the next, and asteroids found only days before their flyby appear in the list regularly. Our server requests a fresh list every three hours; times in the table are shown in your local time zone, with the original UTC time in the tooltip. The "JPL SBDB" link opens the object's page with orbital elements and the full observation history.
