NASA formally announces that asteroid 2024 YR4 now poses "no significant threat" to Earth in 2032 and beyond as the chances of an impact drop to 1-in-59,000 (0.0017%). This means a planetary defense mission to intercept and deflect the object in 2028 during a close flyby of Earth is no longer necessary. 2025-02-24
The European Space Agency announces that the chances of asteroid 2024 YR4 impacting Earth in 2032 has decreased to 1.5% (1-in-67), and is likely to decrease further to less than 1%. 2025-02-21

Astronomers rule out the chances of ~30-meter asteroid 2006 QV impacting Earth in September 2019 by eliminating the possibility of its passing through an area where it would have to be if it were on an impacting orbit. Prior to this, the asteroid had been given a one-in-7,000 chance of impacting Earth. 2019-07-17
