Story summary

Research at the EPSC-DPS2025 meeting in Helsinki highlights the importance of precise targeting for deflecting hazardous asteroids.
Misguided impacts can lead asteroids through "gravitational keyholes," increasing collision risks with Earth.
NASA's DART mission successfully changed the orbit of asteroid Dimorphos in 2022, demonstrating deflection viability.
University of Illinois researchers created "probability maps" to pinpoint optimal impact locations based on asteroid characteristics.
The European Space Agency's Hera mission will enhance these methods by visiting the DART site in December 2026.
