In 2029, Apophis, a ~370m asteroid, will pass just ~31,000 km from Earth. That’s ~1/10 the distance to the Moon. Inside the orbit of geostationary satellites. Visible to the naked eye. Impact risk this time is low, but the flyby could shift its future trajectory. A direct hit would mean a ~1 km crater and regional devastation. That’s why becoming multiplanetary matters.
