Three Asteroids In 'Close Approach' To Earth: NASA

Three large space rocks are hurtling towards earth in the next 24 hours, prompting NASA to list them on their 'close approaches' alert website. 

The first of the asteroids, which has an estimated diameter of up to 17 metres, is known as 2019 AT6 and will skim past the earth's surface at 2:20pm AEST on Tuesday.

While it has been listed on the website, meaning it's relatively close to us humans, in reality it will be more than eight times the average distance between the Earth and the Moon.

To put that in everyday speak, that's more than 3 million kilometres away... so that's quite a long road trip away, even by Aussie standards.

The NEO website shows at least 10 space rocks will be flying 'closely' past earth in the next week.

2019 AT6 will be followed by an even bigger space rock which will pass earth just after 3am on Wednesday morning (AEST).

2019 AM8 is up to 24 metres in diameter but will skim a bit further than its predecessor.

Last but certainly not least, 2019 AG7 will hurtle past us at 9:43am AEST on Wednesday.

The rock measures a whopping 51 metres in diameter and will be the closest of the trio to rocket past earth, at just one and a half million kilometres away from us.

But if you're thinking of jumping into your apocalypse shelters and bracing for the worst, experts ensure these asteroids pose next to no threat to us here on earth.

Senior Systems Scientist at the Australia Telescope Compact Array, Dr Jamie Stevens said these kinds of small body objects are discovered all the time and monitored closely by telescopes and experts to ensure they pose no threat to earth.

"A few organisations around the world are tasked with making sure that we identify these things so that if anything looks to be a threat to earth we can try and do something about it," Stevens told 10 daily.

We are an enormously small target in the giant space... it's very unlikely that something will happen to us or hurt us.

The trio of asteroids coming our way have also been listed as "small bodies".

According to Stevens, this means they're not considering to have enough mass to form themselves into a sphere, unlike a planet or a moon.

Stevens said a maximum of 51 metres in diameter is "very, very small" and added that astronomers would often detect asteroids that are kilometres in diameter.

Being such a small object, Stevens said it means it must have passed pretty close to earth to even be detected but poses "next to no threat".

Even if they were to hit us, it's maybe a size of a small building that would actually impact earth.

That would devastate an area right next to it but barely have any effect otherwise.

Unfortunately for keen sky-watchers Stevens also said the objects would be far too small to be seen from earth even using a telescope.

So go back inside and stay out of that heat that's scorching Australia right now, because there's absolutely nothing to see here.
