An alarming 2020 continues to presentsurprises. On the eve of Christmas, NASA warned earthlings about the potential danger posed by three asteroids flying in space, in close proximity to the Earth.
From the statement of scientists it follows that spaceobjects will not meet with the Earth, but will fly past us at an extremely small distance for a cosmic scale, which is about 3 million kilometers. This will happen on December 25, 2020. The most massive asteroid, which received the marker 501647 (2014 SD224), already flew to Earth in January of this year and will return to an extremely small distance to our planet in December 2021.
Dimensions 501647 (2014 SD224) relativesmall and are only about 200 meters. For comparison, the meteorite that killed the dinosaurs was 15 km in diameter. According to NASA standards, all objects from space are considered potentially dangerous if they fly at a distance of 0.05 astronomical units (7,479,894 km) from Earth and have a diameter greater than 460 feet (140 meters).
