According to the astronomer, anyone with a 200mm telescope should be able to spot the rock on Friday.
But does the “potentially hazardous” asteroid pose any threat to the safety of the planet?
NASA said: “An individual’s chance of being killed by a meteorite is small, but the risk increases with the size of the impacting comet or asteroid, with the greatest risk associated with global catastrophes resulting from impacts of objects larger than one kilometre.
“NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small.
“In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.”
