00:00On July 25, just a day after being detected by the Southern Observatory for Near-Earth
00:10Asteroid Research, SONIR, the 100-meter-wide asteroid 2019 OK made a startlingly close
00:18pass by Earth, coming within a mere 65,000 kilometers.
00:24Responding swiftly, two telescopes from the International Optical Science Network, ISON,
00:29captured images of this celestial object at the European Space Agency's, ESA, request.
00:37These observations enabled ESA's asteroid experts to derive precise data on the asteroid's
00:42position and trajectory.
00:45The released images reveal a dark spot, the asteroid, moving against a backdrop of stars,
00:51which appear as faint streaks due to the telescope's tracking motion.
00:56The unexpected proximity of asteroid 2019 OK underscores the critical need for vigilant
01:02sky monitoring.
01:05Asteroids of this size are relatively common in our solar system, yet they collide with
01:09Earth only about once every 100,000 years.
01:132019 OK follows a highly elliptical orbit, bringing it within Venus's orbit, but it won't
01:20come this close to Earth again for at least another 200 years.
01:25This event serves as a stark reminder of the importance of planetary defense and the need
01:30for continuous observation to safeguard our planet.
