Asteroid Impact Risk Screensaver
The Asteroid Impact Risk screensaver shows the asteroids JPL's Sentry system tracks because they carry a calculated, non-zero chance of hitting Earth, ranked by Palermo scale. Every object listed scores below the natural background risk, and none of this is a prediction. It's free, runs in your browser, and ESC exits.

How the Asteroid Impact Risk screensaver works
The background pipeline reads this from NASA/JPL Sentry and saves a snapshot the saver loads.

Frequently asked questions
- Is this real data?
- Yes — it comes from NASA/JPL Sentry and is refreshed on a schedule.
- Is any of this going to hit us?
- No object here is a prediction. Palermo scale compares an object against the ordinary background chance of a similar impact, and every entry on the list scores below that background — meaning less concerning than the natural rate.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
