What's passing Earth right now

The next notable close approach is (2026 LF1) — here's what a hit would look like.

These objects are NOT on a collision course with Earth. Every figure here is a hypothetical, built from real tracking data.

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.
