The international group of astronomers estimates objects bigger than 460ft (140m) have a one in 100 chance of hitting Earth every 100 years.
But what about the NASA-tracked Asteroid 2020 DR2?
The object is racing around the Sun at speeds of about 20.80km per second or 46,528mph (74,880kmh).
In the event of an impact, the rock would accelerate to 23.59km per second or 52,769mph (84,924kmh).
The asteroid also weighs in at an approximate 308,647,167 tons or 280,000,000,000kg.
