Asteroid 2026 FS5 passed Earth at a distance of 0.120 LD (0.00031 AU \/ 46 133 km \/ 28 666 miles) from the center of our planet at 11:40 UTC on March 22, 2026, becoming the third closest known asteroid flyby within 1 lunar distance recorded so far this year. Its closest point was about 39 762 km (24 707 miles) above Earth\u2019s surface.<\/strong><\/p>\n<\/div>\n 2026 FS5 is the 45th<\/sup> known asteroid to pass within 1 lunar distance of Earth since the start of the year and the third closest so far, after 2026 EM on March 7 at 0.072 LD and 2026 DN5 on February 22 at 0.112 LD.<\/p>\n The object belongs to the Apollo group of asteroids, a class of near-Earth objects whose orbits cross Earth\u2019s path, and has an estimated diameter of 1.4 to 3.1 m (4.6 to 10.2 feet).<\/p>\n It was first observed at MARGO in Nauchny, Crimea, at 21:06 UTC on March 22, about 9 hours and 26 minutes after closest approach. Its flyby took place at a relative velocity of 10.79 km\/s (6.70 mi\/s).<\/p>\n Based on the current JPL orbit solution, 2026 FS5 is not expected to make a closer approach to Earth during the next 180 years. Its next listed approach is on October 5, 2037, when it is expected to pass at 75 LD.<\/p>\n References:<\/p>\n
