When something hits — or just puts on a show — you'll know first. Asteroid Alerts tracks every near-Earth asteroid, fireball, and meteor shower worth your attention, and tells you the one thing that matters each day. • Fireballs — when a bolide lights up the sky and makes the news, you get the alert and the context within the hour. • Tonight — meteor shower peaks, aurora, and what's worth stepping outside for: when to look, where to look, and whether the Moon will ruin it. • Close approaches — every asteroid passing near Earth, with real numbers: distance in lunar distances, size, speed. • The threat list — NASA Sentry's impact-risk objects, tracked continuously, explained plainly. • Spotlight — the asteroids worth knowing about, and why: Apophis's 2029 flyby, Bennu's returned sample, the moon humanity deliberately moved. • Missions — Hera, OSIRIS-APEX, Psyche and the launches that matter. ONE NOTIFICATION A DAY. MAXIMUM. We rank everything happening and send you the single most important thing. No spam, no doom-mongering, no "asteroid the size of a bus" clickbait. FREE, NO ACCOUNT, NO ADS.
