A recently discovered asteroid the size of a football field, called 2017 RW1, must pass by our planet on Monday, September 25. This cosmic stone, measuring 34 to 110 meters in size, is estimated to pass the Earth at a distance of about 10.9 lunar-earth distances, or 4.19 million kilometers.
The asteroid 2017 RW1, belonging to the Apollo group, was first seen on September 12, 2017 with the help of the Pan-STARRS 1 (PS1) telescope, mounted on the top of the Haleakala volcano on the island of Maui in the Hawaiian archipelago. Panoramic Survey The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) includes astronomical cameras, telescopes and a computer center, the joint work of which allows continuous observation of the entire sky in search of moving objects.
Astronomers have found that object 2017 RW1 has an absolute value of 23.7. This asteroid will pass the Earth exactly at 13:29 UTC, moving at a speed of about 12.68 kilometers per second. This object orbits the Sun with a period of 2.1 years and a diameter of about 1.64 astronomical units (1 AU is equal to the distance from the Earth to the Sun).
In the future, repeated approaches of the asteroid 2017 RW1 to the Earth are not anticipated, astronomers report.
To date, scientists have discovered 16,689 near-Earth objects. Only this month 79 new objects of this type were discovered.
