found that celestial objects approaching from the east in the night-time sky can appear stationary due to a quirk of the Earth’s daily rotation and its journey around the sun.

The new discovery comes amid a renewal of public interest in planetary collision in the wake of the hit Netflix film Don’t Look Up, which features Leonardo DiCaprio and Jennifer Lawrence as scientists trying to warn an unreceptive public about a comet that goes on to wipe out mankind.Professor Richard Wainscoat, who led the research team at the University of Hawaii, said people “shouldn’t lose sleep” over the chances of being hit by a devastating asteroid.

Were it not for the phenomenon, asteroids of the size of the 2019 body, known as 2019 OK, would be detectable up to four weeks ahead of impact. Nasa characterises near-Earth objects as those that come within 28 million miles of Earth’s path around the sun.
