NASA is currently tracking three objects near the Earth (NEO) due to fly past the Earth on November 20. Worryingly, two of the three were only discovered this past weekend, which again aroused tensions over the planetary defense.
The first of Wednesday's cosmic flyby and the largest, measuring 157.5 ft to 360.8ft (48 to 110 meters) across, will be the asteroid 2019 UK6, which will pass around 6.20 AM GMT (1.20 am EDT) . It is 2019 UK6 that we had the most prior warning about, as it was first observed on October 24.
NEO 2019 UK6 is an Amor asteroid that orbits the Sun and the Earth, sometimes, but very rarely, crossing the Earth's path. Apollo asteroids, on the other hand, cross the Earth's orbit as the planet orbits the sun.
The second of Wednesday's flyby will be WF 2019, first discovered by NASA's asteroid hunter just two days ago on November 17. Estimated to be about 24 feet wide, it will make its closest earth approach at about twice the distance to the moon, so no danger of an extinction event there anyway.
The latest is 2019 WE, also discovered at the last second on November 17. This asteroid sails past our planet at a distance of about 1.3 million kilometers.
According to NASA's Center for Near-Earth Object Studies (CNEOS), all three will have what is called "Near the Earth is approaching," but unfortunately no one is believed to pose any threat.
