Three asteroids on 'close approach' course for Earth this weekend

Tens of millions of years ago, a giant asteroid is thought to have crashed to Earth, triggering a series of cataclysmic events that killed the majority of animal and plants. The biggest measures 30 metres across - more than twice the length of a standard city bus.

Asteroids regularly pass close to Earth, so there's no need to panic.

'As they orbit the Sun, near-Earth objects can occasionally approach close to Earth, ' warned Nasa.

It's also important to remember that a "close approach" might not be as close as you think.

The conspiracy theorist said: "Three asteroids are on their way this weekend, we just found out within an hour".

But what's exciting is the fact that three will pass near Earth on Sunday between 1am and 6am AEST. Around 14:03 GMT, an asteroid, 2018 VS1, will pass the Earth.

Experts at the Jet Propulsion Laboratory in California believe that it's between 13 and 28 metres wide. The asteroid will pass within roughly 381,000 kilometres of Earth. The next fly-by will take place just 16 minutes later, at 1:19 am.

Scientists predict that the largest of the space rocks, dubbed 2018 VR1, is up to 100 feet (30 metres) wide - as long as a blue whale. The closest travelling NEOs that will approach Earth on Saturday can only reach 20 metres.

It zoomed past Earth on October 31, 2015, coming within 302,000 miles of our planet.

According to some estimates, Earth is due for a big collision.

People here on Earth will be able to see the star of the show - asteroid 2018 VX1 - online at about 1:20 p.m. EST (18:20 UTC), "the moment of its minimum distance from us", Masi said. Scientists say that the closer to the object threatens the Earth.

Racing through speeds of around 6.06km per second, Asteroid VX1 is approximately somewhere between 25.9ft and 59ft in diameter.

To you sky-watchers out there, unless you have a satellite handy, don't bother gazing upwards for any of the asteroids - they're just too small and too far away.

It's possible to then compare the images and then look out for small objects that have changed position.
