Recent observations from the ATLAS survey revealed something unsettling: small space objects don’t always behave the way our models predict. Unusual motion and acceleration patterns from object 3I/ATLAS challenged the standard explanations of sunlight pressure and outgassing, exposing how thin our margin for surprise really is.
Now attention shifts to Apophis. On April 13, 2029, the asteroid will pass just 32,000 km from Earth — closer than many satellites. Space agencies say the flyby is safe, but safety depends on predictability, and predictability is exactly what new data has put under scrutiny.
That’s why scientists are preparing spacecraft and high-resolution instruments to monitor Apophis in real time, tracking even the smallest shifts in its spin, surface, and trajectory. Because in planetary defense, seeing a change early makes all the difference.
