Professional and amateur astronomers are gearing up to observe asteroid 1999 KW4 – oddly shaped, about a mile wide, with a companion moon – around its closest approach on May 25, 2019. Charts here for amateur observers across the globe.

A small asteroid – now designated as 2019 FC1 – flew closer to us than the moon on March 28, 2019. Astronomers detected it 1 day later. It’s the largest of 14 asteroids to pass closer to us than the moon since 2019 began.

The Exoplanet Team, led by the Observatoire de Paris, announced this week that the list of known exoplanets – planets orbiting distant stars – has grown to 4,001!
