Every rock that passes close.Tracked, named, and measured — in one place.
Near-Earth asteroids — their distance in lunar distances, their size, their speed. The ones NASA is watching, gathered where you can see them.
Something crosses our orbit almost every week. Most of us never hear a word.
Dozens of asteroids swing past inside the Moon's distance every year — some the size of a car, a few the size of a building. Astronomers see them coming. The data is public. It's just scattered across observatory feeds and catalog numbers, where no one thinks to look.
This gathers them into one clear view: what's coming, how close, how big, how fast. Not doom — just the quiet fact of a busy sky, made legible.
Distance measured in Moons, not millions of miles.
A "lunar distance" is the gap between here and the Moon — about 239,000 miles. When a rock passes at 2.8 lunar distances, you can picture it: three Moons out, and closing. It turns an abstract number into something your body understands.
Four numbers. Nothing hidden.
Its name in the catalog — the rock, on the record.
How many Moons away at closest approach.
Estimated diameter — a car, a house, a stadium.
How fast it's moving relative to Earth, in km/s.
When it reaches its nearest point to us.
Its path across the sky, drawn toward Earth.
Every approach is drawn from the Center for Near-Earth Object Studies — the same catalog the world's astronomers use. No guesses, no embellishment.
Surveys sweep the sky every clear night and refine each orbit as new observations arrive. The list updates as the sky does.
Close is not the same as dangerous. We show you the pass exactly as it is — the wonder of a crowded neighborhood, not a warning siren.
See the sky. Then let it watch for you.
The tracker lives inside Magna Earth — $14/mo or $129/yr — with the alerts, the scanner, and the rest of the living Earth.
