The famed astrophysicist posted a photo of the giant space rock, known as 2018VP1, on his Instagram, saying the asteroid is hurtling towards Earth at an estimated speed of 21,300 miles per hour. But “it’s not big enough to cause harm”, he added.
The asteroid 2018VP1 has been on the radar since November 2018, when it was first detected by the Palomar Observatory in California.
However, 2018VP1 "poses no threat to Earth," NASA said in a statement.
