How many asteroids pass Earth in a week?

NASA's feed typically lists dozens of catalogued close approaches across a seven-day window, the great majority of them small objects passing well beyond the Moon's orbit.

Why is the window limited to seven days?

NASA's Near Earth Object Web Service feed endpoint returns a maximum of seven days per request, so Orbitfall's week view matches that limit.

Can I see a specific date range?

Yes. The tracker's custom range option lets you pick any start and end date within the seven-day limit.

Asteroids Passing Earth This Week

The next seven days of catalogued asteroid close approaches, built from NASA's near-Earth object feed and ranked by the Orbitfall Index.

A week is the natural unit for asteroid watching. Individual days are often empty or dominated by one small object, while a seven-day window shows the real rhythm of near-Earth traffic — a steady stream of catalogued rocks passing at distances from a fraction of the Moon's orbit out to tens of lunar distances.

This week NASA's feed lists 31 catalogued close approaches. The closest pass belongs to 2018 SP2.

Reading a week at a time

Ranking by date tells you when things happen; ranking by the Orbitfall Index tells you which pass is worth reading about. The index blends four inputs — proximity in lunar distances, estimated size, relative velocity, and NASA's potentially hazardous flag — into a single 0–100 score. A large object passing far away and a tiny one skimming past can land on similar scores for very different reasons.

Open the Orbitfall tracker to sort the same week by closest distance, largest size, fastest velocity, or approach date, or to narrow the window to a custom range.

What changes between weeks

Two things shift the list. First, discovery: survey programs add new near-Earth objects constantly, and a rock found tonight can appear in this week's list tomorrow. Second, refinement — every extra observation tightens an orbit, so predicted miss distances move slightly as the approach date nears. Objects catalogued years ago have approach times pinned down to minutes.

For the narrower view, see asteroids passing Earth today. For background on the data pipeline behind these numbers, see the NASA asteroid tracker page and how NASA tracks asteroids.
