# $ROCKS · New near-Earth asteroids

Near-Earth asteroids and comets whose first observation fell in a month, as NASA JPL's Small-Body Database lists them: every object in its near-Earth group, counted by the date of its first observation. Read again every day, so an object found later in older images moves to the month it was first seen: old months grow, and the record keeps each revision beside the number as first published. A handful of objects with no first observation date, or only a year, belong to no month. Counted from January 2010.

| Field | Value |
| --- | --- |
| Newest complete period | Oct 2026: 258 objects, score 0, Quiet |
| Source | NASA JPL Solar System Dynamics, Small-Body Database Query API, near-Earth objects (https://ssd-api.jpl.nasa.gov/doc/sbdb_query.html) |
| Terms | JPL asks for a citation (Solar System Dynamics, https://ssd.jpl.nasa.gov) and names no licence for the API. |
| Cadence | Monthly. JPL adds objects as the Minor Planet Center designates them, within days; a month prints seven days after it ends and keeps growing as earlier sightings are linked. |
| Grade | display |
| Rulebook | Rulebook v0.2, 2026-10-04 |

## Settlement

Why this grade: A month's count grows for years as older images of new objects are found, so the number as first published is not the number today. JPL names no licence. Shown, not settled on.
What it costs to move: Not practical. An object enters the list only after the Minor Planet Center confirms its orbit.
When the source is late: A month prints seven days after it ends. If the newest month has no object, the read fails and the month stays open. A month JPL never lists is void.
Precision: Whole objects, by first observation date as JPL gives it.

## Asked often

**How many new near-Earth asteroids are found each month?** 258 near-Earth asteroids and comets were first observed in Oct 2026, as NASA JPL's Small-Body Database lists them, counted by Tickerz.

**Where does the $ROCKS number come from?** Tickerz reads it from NASA JPL Solar System Dynamics, Small-Body Database Query API, near-Earth objects. Monthly. JPL adds objects as the Minor Planet Center designates them, within days; a month prints seven days after it ends and keeps growing as earlier sightings are linked. Each number is kept as it was first published, with a timestamped proof, and any later revision is shown beside it.

**Can I download the $ROCKS data?** Yes, free and with no key: the full history as JSON at https://tickerz.com/api/indices/rocks and every period as CSV at https://tickerz.com/api/indices/rocks/history.csv.
