In yet another cosmic barrage of boulders and debris, NASA is warning of at least five close asteroid flybys this week, just days after Japan’s space agency announced it would be extending its asteroid-hunter mission.

To kick things off, on September 21 the 10-meter and 16-meter 2020 RQ6 and 2020 SJ2 will shoot past the Earth at distances of 1.2 and 1.4 million kilometers respectively.

Before anyone can breathe a sigh of relief, however, three more Near-Earth Objects are expected to fly past on September 22.

At 50m in diameter, or as tall as the Arc de Triomphe, the largest of the three, named 2020 RD5, will pass the Earth at 61,000 kph at a mercifully safe distance of four million kilometers.
