Currently, we know of about roughly 25,000 near-Earth objects larger than 460 feet in diameter.
The space rock's last close approach to Earth took place in February this year. And the next one will occur in November 2020.
"A near-Earth asteroid is considered 'potentially hazardous' if its orbit approaches the Earth's orbit to within approximately 4.6 million miles, or about 19 lunar distances, and its size is greater than roughly 140 meters [around 460 feet,]" Chodas said.Despite the fact that 481394 is classed as potentially hazardous, projections show that it has no chance of striking the Earth in the next two centuries or so.
Currently, we know about roughly 25,000 NEOs larger than 460 feet in diameter with Chodas noting that we have discovered about 35 percent of the total figure.
