Nasa has warned a GIGANTIC asteroid will rock the earth today.
Asteroid 7482 (1994 PC1) is estimated to be about 3,551 feet long – making it larger than any building on Earth.
It is expected to pass our planet safely at 4:51pm EST (9:51pm UK time) on January 18.
Nasa is keeping a close eye on the giant space rock and has added it to the “close approach” database.
The asteroid is expected to pass Earth at a distance of about 1.2 million miles – almost five times the distance between our planet and the Moon.
This seems like a reasonable distance, but it’s a spatially close distance.
Nasa considers anything that passes within 120 million miles of Earth as a Near-Earth Object (NEO).
Thousands of NEOs are tracked by scientists to see if they are on their way to collide with our planet.
Any fast-moving space object within 4.65 million miles is considered “potentially dangerous” by cautious space organizations.
A small change to their orbits could spell disaster for the Earth.
Asteroid 7482 (1994 PC1) will travel at just under 44,000 miles per hour, according to Nasa.
This asteroid is expected to pass through Earth’s orbit every 30 years or so.
It is not expected to come this close again in 200 years.
The Virtual Telescope Project will stream the asteroid’s close encounter if you want to watch it live.
Astronomers are currently tracking nearly 2,000 asteroids, comets and other objects that threaten our pale blue dot, and new ones are found every day.
Earth has not seen an asteroid of doomsday scale since the space rock wiped out the dinosaurs 66 million years ago.
However, smaller objects capable of flattening an entire city crash into Earth frequently.

Luckily, Nasa doesn’t believe any of the NEOs it has its eyes on are in the process of colliding with our planet.
However, that could change in the coming months or years as the space agency continually revises the predicted orbits of objects.
“Nasa doesn’t know of any asteroids or comets that are on a collision course with Earth, so the probability of a major collision is quite small,” Nasa said.
“In fact, as best we can tell, there is no large object capable of hitting Earth at any time in the next few hundred years.”
Even if they hit our planet, most asteroids won’t wipe out life as we know it.
“Global catastrophe” is only triggered when objects larger than 900 meters crash into Earth, according to Nasa.
