What's passing Earth right now

The next notable close approach is Apophis — and it comes startlingly close.

The benchmark close approach of our lifetime. In 2029 Apophis passes inside the ring of geostationary satellites — closer than many of the things humans put in orbit.

These objects are tracked and are NOT on a collision course with Earth. “If it hits” is a hypothetical to show scale.

The object that briefly rose to the highest impact odds since 2004 — then was ruled out in three weeks. A small-asteroid case study in how the system works.

Ruled out after follow-up observations. Impact odds for 2032 fell roughly 600× as the orbit was refined — the normal, reassuring arc.

How this works — and why nothing here is a prediction
01

Real tracked objects

Every object is pulled from NASA/JPL, ESA and the Minor Planet Center. Nothing here is invented or gamified.

02

Translated to scale

We turn diameters, distances and velocities into plain language — “inside the Moon’s orbit,” “between Tunguska and a bomb.”

03

Ranges, never certainty

Derived figures are shown as ranges with their assumptions. Astronomers rule out almost every flagged object as data improves.
