An asteroid nearly the size of a city block will fly by Thursday night.
According to astronomers, the asteroid named 2012 LZ1 is approximately 1,650 feet wide and will come within 14 lunar distances of the Earth about 8 p.m. Lunar distance is a measurement of the distance from the Earth to the moon, which is nearly 238,855 miles.
Experts say there is no danger of an impact from the passage of the asteroid.
The asteroid was discovered Sunday by Rob McNaught and his colleagues, who just happened to be looking through the Uppsala Schmid telescope, located at Siding Spring Observatory in Australia.
On Thursday evening, the newly discovered space rock will come within roughly 3.35 million miles of our planet, which is about 14 times the distance between Earth and the moon.
The asteroid won't be visible with the naked eye. Click here to watch the event on the Slooh Space Camera website.
