NASA is keeping its eye on a gigantic asteroid that’s just over a month away from a close approach with Earth.
The ‘potentially hazardous’ space rock is said to be up to 4,265 Füße breit.
That makes it almost three times as big as the Empire State Building.
The Empire State Building stands at around 1,453 feet tall so would pale in comparison to Asteroid 138971 (2001 CB21).
Nasa has put the asteroid on its ‘Earth Close Approaches’ aufführen.
The good news is it’s not expected to hit Earth.
An asteroid of this size would do some serious damage.
It should shoot past us on March 4 from an estimated distance of 3million miles away.

In comparison, the Moon is only about 238,900 miles from us.
A few million miles may sound pretty far away but it’s actually quite close in terms of space.
Nasa considers anything passing near Earth’s orbit a Near-Earth Object (NEO).
Tausende von NEOs werden von Wissenschaftlern verfolgt, um zu überwachen, ob sie auf Kollisionskurs mit unserem Planeten sind.
Jedes sich schnell bewegende Weltraumobjekt, das hereinkommt 4.65 Millionen Meilen gilt als “möglicherweise gefährlich” von vorsichtigen Weltraumorganisationen.
Eine kleine Änderung ihrer Bahnen könnte eine Katastrophe für die Erde bedeuten.
Nasa thinks Asteroid 138971 (2001 CB21) will speed past Earth at around 27,000 miles per hour in the early hours of March 4.
That means the space agency has got just over a month to prepare for the flypast.
Plans to save Earth from asteroids
Some experts are worried that Earth isn’t yet ready to defend itself from potentially deadly asteroids.
SpaceX CEO Elon Musk once sparked concern by tweeting: “a big rock will hit Earth eventually & we currently have no defence.”
Nasa is looking into to some defence methods though.
It recently launched its Double Asteroid Redirection Test mission.
NASA sagte: “DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact.”
The DART craft should slam into a small asteroid called Dimorphos in September with the aim of moving it off course.

Nasa has revealed stunning footage of a solar flare in action.
Und, the US space agency is planning for a ‘golden asteroid’ probing mission to launch this summer.
