Every near-Earth object NASA is tracking this week, pulled live and updated daily. Or pick any date back to 1995 and see what was passing on the day you were born.
Each object positioned by how close it comes and how fast it moves. Size is diameter; color is NASA's hazard flag.
Objects NASA detected per year. This isn't fewer asteroids — it's better eyes. The rise is our own observational power.
Émilie du Châtelet translated and extended the mathematics of Newtonian motion — the framework that lets us predict exactly where a body in space will be. Three centuries later, that same math powers NASA's tracking of the rocks crossing Earth's neighborhood. This piece pulls that tracking data live.
