Asteroids Passing Earth Today

Asteroids pass Earth every single day. Most of them are small, most of them are far away, and almost none of them make the news. The list below is today's set of catalogued close approaches, pulled live from NASA's Near Earth Object Web Service and sorted so the most notable pass sits at the top.

Today's close approaches

• Asteroid 2018 SP2Orbitfall Index 51/100

  Close approach Wed, Sep 30, 2026 — misses Earth by 1,927,097 km (5.01 lunar distances) at 14.3 km/s. Estimated diameter 29–65 m. NASA does not list it as potentially hazardous.

• Asteroid 2002 PN6Orbitfall Index 21/100

  Close approach Wed, Sep 30, 2026 — misses Earth by 62,349,989 km (162.13 lunar distances) at 1.6 km/s. Estimated diameter 176–393 m. NASA does not list it as potentially hazardous.

• Asteroid 2012 VT6Orbitfall Index 20/100

  Close approach Wed, Sep 30, 2026 — misses Earth by 22,754,832 km (59.17 lunar distances) at 6.4 km/s. Estimated diameter 64–143 m. NASA does not list it as potentially hazardous.

• Asteroid 2014 QJ33Orbitfall Index 19/100

  Close approach Wed, Sep 30, 2026 — misses Earth by 16,885,637 km (43.91 lunar distances) at 6.0 km/s. Estimated diameter 48–108 m. NASA does not list it as potentially hazardous.

• Asteroid 2010 TW54Orbitfall Index 12/100

  Close approach Wed, Sep 30, 2026 — misses Earth by 17,457,205 km (45.39 lunar distances) at 4.5 km/s. Estimated diameter 8–18 m. NASA does not list it as potentially hazardous.

This score ranks how notable the asteroid approach is. It is not an impact prediction.

How to read today's list

Each entry carries the same measurements the Orbitfall asteroid tracker uses:

• Miss distance in kilometers — how far the asteroid's closest point is from Earth's center.
• Miss distance in lunar distances — the same figure divided by 384,400 km. See lunar distance explained.
• Estimated diameter — a min–max range derived from the object's brightness, not a direct measurement.
• Relative velocity — speed relative to Earth, in kilometers per second.
• Hazard status — whether NASA classes the object as a potentially hazardous asteroid.

Why today's list changes

The feed is rebuilt from NASA data each time you load the page, and it rolls over at midnight UTC rather than in your local time zone. New objects are also added continuously: survey telescopes discover near-Earth asteroids almost nightly, and an object found last night can appear in today's list for the first time. Orbits are refined as more observations arrive, so distances can shift slightly between updates.

If today looks quiet, that is normal. Have a look at asteroids passing Earth this week for a wider window, or near-Earth objects today for the broader NEO picture.

Does a close approach mean danger?

No. A close approach is a scheduled flyby computed from a known orbit — it is astronomy's way of saying "this object comes within a certain distance on this date." Read what a close approach actually means and how NASA tracks asteroids for the full picture. The Orbitfall Index ranks how notable a pass is — it is not an impact prediction.

Frequently asked questions

How many asteroids pass Earth today?

NASA's near-Earth object feed usually lists a handful of catalogued close approaches on any given day. Most are small objects passing several lunar distances away.

Is an asteroid going to hit Earth today?

No catalogued asteroid is on an impact trajectory for today. Orbitfall lists scheduled close approaches from NASA data; it is not an impact-warning system.

How close is close?

Miss distance is shown in kilometers and in lunar distances. One lunar distance is about 384,400 km, the average Earth–Moon gap.
