Unusual months1
- Counts
- Close approaches to Earth by near-Earth asteroids and comets within 0.05 astronomical units (about 7.5 million kilometres, under twenty lunar distances) in a month, by the time of closest approach, as NASA JPL's Close Approach Data lists them. Read again every day, so a rock found after it passed is added to its month, and the record keeps the revision. Times are JPL's (TDB, about a minute off UTC). Counted from January 2010.
- Why it is here
- Dozens of known rocks pass within twenty lunar distances of Earth every month, and over two hundred in a busy one.
- Cadence
- Monthly. JPL updates the list as orbits are computed; a month prints seven days after it ends. Newest complete month Oct 2026. Read Nov 13, 07:40 UTC.
- Baseline
- The prior 24 months, 12 needed.
Quote this number
180 known asteroids and comets came within 7.5 million kilometres of Earth in Oct 2026, according to Tickerz, which counts them from NASA JPL data.
Asked often
- How many asteroids pass close to Earth each month?
- 180 asteroids and comets passed within 0.05 astronomical units of Earth in Oct 2026, as NASA JPL's close approach list gives them, counted by Tickerz.
- Where does the $FLYBY number come from?
- Tickerz reads it from NASA JPL Solar System Dynamics, SBDB Close Approach Data API, Earth, 0.05 au. Monthly. JPL updates the list as orbits are computed; a month prints seven days after it ends. 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 $FLYBY data?
- Yes, free and with no key: the full history as JSON at https://tickerz.com/api/indices/flyby and every period as CSV at https://tickerz.com/api/indices/flyby/history.csv.
List it
No listing kit for $FLYBY yet. A kit sets its strikes from 14 published numbers. This index publishes one a month and has none yet.
Resolution
- Index
- $FLYBY Asteroids that passed close to Earth. Rulebook v0.2, 2026-10-04.
- Prints
- Monthly. JPL updates the list as orbits are computed; a month prints seven days after it ends. The newest complete month is on the record after the daily proof at 12:40 UTC.
- As first published
Oct 2026 is not timestamped yet. The daily proof at 12:40 UTC adds it.
The number as first published is final for settlement. A revision by the source is shown beside it and never replaces it.
- Fallback
- A month prints seven days after it ends. If the newest month has no approach, the read fails and the month stays open. A month JPL never lists is void.
- Precision
- Whole close approaches within 0.05 au, by JPL's time of closest approach.
- Cost to move
- Not practical. The list is computed from confirmed orbits.
- Grade
- display. Many close approaches are found only after the rock has passed, so a month keeps growing. JPL names no licence. Shown, not settled on.
- For a rulebook
- Settle on the number Tickerz first recorded for $FLYBY for the month named in the contract, published at tickerz.com/x/flyby and in GET /api/indices/flyby, timestamped daily in Bitcoin with OpenTimestamps.
