Summary The asteroid Apophis made one of its close encounters with earth in April 2021. Asteroid watchers paid close attention because each close encounter alters the orbit of the asteroid by an amount that is hard to predict due to inaccuracies in velocity and distance measurements. Now that it is leaving Earth's vicinity, new measurements can refine the details of its new orbit. And we seem to be perfectly safe from Apophis until 2116.
