The space rock known as 2014 JO25 will shoot past us and its the closest this one will get for the next 500 years.
At around 1.8 million kilometres away, the asteroid has been classed as a near Earth object (NEO) and is almost five times the distance between our planet and the moon.
Little is known about the asteroid which has been colloquially dubbed ‘The Rock’ as it was discovered just three years ago by astronomers at the Catalina Sky Survey in Arizona.
But what NASA and other experts do know is the asteroid is up to 1.4 kilometres in length and is so reflective that it will be visible with the naked eye from Earth when it whizzes past us at 33 metres per second.

Although we are not under-threat from the relatively small space rock, online observatory Slooh, which will be broadcasting the flyby from 11PM GMT and shown on Express.co.uk, says that it is still potentially hazardous.
It said in a statement: "Even a 30 metre sized asteroid can cause significant damage to a major city.
"Even a 30 metre sized asteroid can cause significant damage to a major city."
"While not causing an extinction level event, an impact from an asteroid the size of 'The Rock' would have a calamitous effect at the local and even regional level.”
NASA added: “Small asteroids pass within this distance of Earth several times each week, but this upcoming close approach is the closest by any known asteroid of this size, or larger, since asteroid Toutatis, a 3.1-mile (five-kilometre) asteroid, which approached within about four lunar distances in September 2004.

Amazing facts about Asteroids
Tue, April 4, 2017
The first asteroid was Ceres, discovered by Giuseppe Piazzi in 1801. There are currently over 600,000 known asteroids in our solar system. Most asteroids are found orbiting in the Asteroid Belt, a series of rings located between the orbits of Mars and Jupiter.

There are Millions of Asteroids in the solar system, usually found in the Asteroid belt between Mars and Jupiter, however those in that pass the Earth are called Near-Earth objects
“The next known encounter of an asteroid of comparable size will occur in 2027 when the half-mile-wide (800-meter-wide) asteroid 1999 AN10 will fly by at one lunar distance, about 236,000 miles (380,000 kilometres).”
