2019 OU1 will arrive on August 28 within 639,000 miles of Earth. As reported by Fox News, the diameter of the asteroid is between 233 feet and 524 feet. NASA data shows that 2019 OU1 is traveling at a speed of eight miles per second.
Although the asteroid is expected to pass safely, its size and distance from the earth make it "potentially dangerous".
NASA last June published a report on handling asteroids and comets that are located within 30 million miles of our planet.
Linda Johnson, NASA's Planetary Defense Officer, stated that they "already have significant scientific, technical and operational capabilities," but the new plan could "build our nation's commitment to development and cooperation." significantly improve the ability of international partners to respond effectively when a new potential asteroid effect is identified. " the Double Asteroid Redirection Test (DART), which could distract asteroids from Earth orbit.

"Ultimately, it's about protecting the only planet we know properly. Now life is to be hosted, and that's the planet Earth."
Most asteroids in the solar system are in the asteroid belt between Mars and Jupiter.
The total mass of the belt is 22 percent of that of Pluto.
The upper estimate of the 2019 OU1 diameter would put it in 15th place in the list of tallest buildings in Britain, if it were a skyscraper in the UK.  It would only be 1ft just before 20 Fenchurch Street in the City of London.
Manchester's Beetham Tower and Deansgate Square – South Tower would be the only buildings outside of London that are taller.
17 buildings in Greater London would be under construction.
