Summary

Story summary

Researchers from the University of Tokyo presented findings showing an asteroid's spin results from collisions and internal friction.
They note many asteroids are loose clusters rather than solid, which affects responses to spacecraft impacts.
A team from the University of Illinois developed probability maps to identify safe strike zones and prevent drift into gravitational keyholes that could redirect them toward Earth.
The findings could enhance planetary defense strategies.
