Recently discovered

Several near-Earth objects are found every night. Most are small, most are never seen again for years, and a good number of the things on the confirmation page turn out not to be new at all.

Awaiting confirmation

Live

These are candidates, not discoveries. Each is a moving object someone has reported that may be a near-Earth object; the score is the Minor Planet Centre's estimate of how likely that is. Most entries leave the page within days — confirmed, identified as something already known, or discarded.

122 candidates. A temporary designation is not a name: it is discarded once the object is confirmed and properly designated, or once it is discounted.

The NEO Confirmation Page lists CANDIDATES, not discoveries. An entry may turn out to be an already-known object, a main-belt asteroid rather than a near-Earth one, or an artefact; most entries leave the page within days. The score is the MPC's estimate of how likely the object is a NEO, not a probability that it exists.

Newly catalogued

Live

Objects whose first observationfalls in the last sixty days and which now have a computed orbit in JPL's small-body database. First observation is not the same as announcement: an object is often recovered in archival images taken before anyone realised it was there.

The 60 most recent of 359 entries. MOID is the minimum distance between the two orbits, not between the two bodies — an object with a small MOID need never come close in practice.

“Potentially hazardous” is a category, not a warning

An object is classified potentially hazardous if its orbit comes within 0.05 astronomical units of Earth's and it is bright enough — absolute magnitude 22.0 or brighter — to be roughly 140 metres across or larger. Both tests include their boundary. Both conditions are about the orbit and the size, and neither says anything about whether an impact is expected. Thousands of known objects meet the definition — a few thousand, and rising as surveys find more, which is why no fixed number is written here. None of them is on a collision course.

Provenance

Every figure here is JPL's or the Minor Planet Centre's. AsteriaStar computes no impact probability and applies no danger rating of its own: where a hazard is named, it is on a scale the issuing agency defined, quoted as they define it. A close approach is described by its distance and its uncertainty, because that is what the data says. Objects pass within a few lunar distances routinely, and the word for that is “routine”.

Recently observed near-Earth objects from JPL Solar System Dynamics / CNEOS, fetched from https://ssd-api.jpl.nasa.gov/sbdb_query.api?fields=full_name,pdes,neo,pha,H,diameter,first_obs,class,moid&sb-class=IEO,ATE,APO,AMO&sb-cdata=%7B%22AND%22%3A%5B%22first_obs%7CGE%7C2026-07-18%22%5D%7D&sort=-first_obs&limit=1000. A new NEO enters the database once its orbit is computed, which happens over days. Six hours cannot delay one meaningfully, and the date window only advances once per day.

`first_obs` is the date of the FIRST OBSERVATION used in the orbit solution — not the date the object was announced, and not the date anyone recognised it as new. Absolute magnitude H is a brightness, not a size; a diameter appears only where one has actually been measured or modelled.

NEO Confirmation Page (unconfirmed candidates) from IAU Minor Planet Center, fetched from https://minorplanetcenter.net/Extended_Files/neocp.json. The page is regenerated as observations arrive, and entries live on it for hours to days. Ten minutes bounds how long a new candidate is missing while keeping the request rate to a small file trivial.

These are CANDIDATES awaiting confirmation, not discoveries. An entry may prove to be an already-known object, not a near-Earth object at all, or an artefact, and most leave the page within days. The score is the MPC's estimate of how likely the object is a NEO — it is not a probability that the object exists, and it is not an impact risk.
