NASA predicts the space rock will swing by our planet just minutes before midnight on Friday, January 10. When this happens, NASA said the rock will make a “close approach” to Earth. Dubbed Asteroid 2019 UO, NASA’s trackers confirmed the rock’s trajectory in October 2019. Since then, NASA has calculated the asteroid’s size, speed and orbit to determine whether it poses a threat to Earth. Due to its impressive size and close brush with Earth, NASA’s astronomers dubbed 2019 UO a “potentially hazardous asteroid” or PHA.

NASA said “this allows the possibility of a future collision” even if an initial flyby is harmless. On January 10, Asteroid 2019 UO will approach the planet at breakneck speeds of around 9.40km per second or 21,027mph (33,840lm/h). NASA also estimates the rock measures somewhere in the range of 820ft to 1,804ft (250m to 550m) in diameter. At the upper end of NASA’s scale, the asteroid is comparable in height to Moscow’s Ostankino Tower. At the lower end of the scale, the asteroid is about as tall as the Golden Gate Bridge in San Francisco, US. READ MORE Yellowstone volcano hit by1,217 earthquakes in 2019 - Is it awakening? According to the European Space Agency (ESA), there are currently 21,702 known NEAs or Near-Earth Objects – space rocks that sometimes cross Earth’s orbit. On top of the extensive list, ESA lists another 997 asteroids that could pose a “risk” to Earth’s safety. Thankfully, NASA does not expect Asteroid OU to come close enough next Friday to strike the planet. At its closest, the asteroid will approach Earth from a distance of about 0.03021 astronomical units. A single astronomical unit is the average distance from our planet to the Sun or about 93 million miles (149.6 million km). Trending In the words, Asteroid OU will miss the planet by a safe margin of about 2.8 million miles (4.5 million km). After the safe flyby, NASA estimates the rock will visit Earth’s corner of space again on Novemb
