Last week, asteroid 2012 TC4 made a close shave with Earth, as it soared past at a distance of just 27,000 miles above the surface.
And experts have warned that a second bus-size asteroid will zoom past our planet again today at half the distance between the Earth and the moon.
Asteroid 2017 TD6 will fly 119,000 miles (191,000 km) from Earth at 19:53 BST (14:53 EST) today – but thankfully, experts predict there is no threat of it hitting our planet.
The near-Earth asteroid was discovered by the Pan-STARRS survey in Hawaii last Wednesday.

The asteroid was discovered is estimated by Nasa’s Centre for Near Earth Object Studies to measure between 9.9 and 22 metres wide.
It will fly between Earth and the moon today, according to several observatories that have been tracking the asteroid in the last few days.
Thankfully, experts predict that there is no threat that the asteroid will hit Earth.
Following today’s pass, 2017 TD6 will then pass by the moon tomorrow at 07:06 BST (02:06 EST).
Its next pass with Earth is predicted to be on May 29 2018, although it is unclear how close it will be.
While 2017 TD6 is expected to miss our planet, if it did hit Earth, it could lead to a much more devastating level of impact than the 18 metre (59 foot) asteroid that hit the city of Chelyabinsk in Russia in 2013.
That particular blast injured about 1,500 people, and damaged over 7,000 buildings.
The passing comes just a week after asteroid 2012 TC4 flew by at just one-eighth of the distance between Earth and the moon.

During its journey, the asteroid narrowly missed communications satellites orbiting 22,236 miles above Earth.
But in one of its next passes with Earth, experts suggest that 2012 TC4 may not miss.
Rudiger Jehn, a mission analyst at the European Space Agency, said: ‘We know today that it will also not hit the Earth in the year 2050, but the close flyby in 2050 might deflect the asteroid such that it could hit the Earth in the year 2079.’
The odds of an impact 62 years from now are now placed at about one in 750.
