"In the order of things people should be worried about, near-Earth objects
isn't highest on the list," Johnson said, according to (https://www.express.co.uk/news/science/1170958/nasa-asteroid-earth-near-earth-objects-space-end-of-world) Express .
"We also found a near-Earth object
in the search field on April 25," Christensen said.
In technical terms, 2019 NJ2 is a Near-Earth Object
(NEO) that's classified by NASA as a Potentially Hazardous Asteroid (PHA) even though the big rock is flying relatively far from us.
Therefore 'Oumuamua is not, strictly speaking, a near-Earth object
"I was not expecting to see anything like this during my career, even though we knew it was possible and that these objects exist," said Davide Farnocchia, a navigational engineer with Nasa's Center for Near-Earth Object

8 ( ANI ): NASA's Near-Earth Object
Wide-field Infrared Survey Explorer (NEOWISE) probe has found a never-before-seen asteroid - its first such discovery since it was brought out of hibernation last year.
"To put it another way, that puts the current probability of no impact in 2032 at about 99.998 percent," said Don Yeomans, manager of NASA's Near-Earth Object
Program Office at the Jet Propulsion Laboratory in Pasadena, California.
"The odds of a near-Earth object
strike causing massive causalities and destruction of infrastructure are very small," said Holdren, "but the potential consequences of such an event are so large that it makes sense to take the risk seriously."
