asteroid earth flyby
An asteroid bigger than the Golden Gate Bridge is careering toward Earth at breakneck speed. What's even more alarming is that experts admit it's "potentially hazardous" to our world.

Astronomers have been following asteroid 2017 VR12 since it was detected in November last year. NASA says that the enormous space rock will shave past our planet in the early hours of Wednesday morning.

Measuring up to 470 meters (1,542ft) in diameter the rock is travelling through space at 14,093mph (22,680kph). Because it will come so close to Earth and is big enough to cause significant damage, if it were to strike, the Minor Planet Center designated the asteroid as "potentially hazardous."

However, fear not, it will not crash into Earth, rather it will pass by at about three times the distance of the moon. It will be nearly 1.4 million km from Earth (870,000 miles) at its closest point during the flyby.

The asteroid is a very good radar target for professional astronomers while amateurs might be able to catch it with smaller telescopes.

NASA's calculations predict it will be at least 177 years before the asteroid again comes as close to Earth as it will be on Wednesday. Ruptly will be live streaming the close encounter with the asteroid through Virtual Telescope's super high-powered telescope.
