Asteroid EB4 is creeping ever closer to the unaware planet with every passing second, threatening a close orbital approach as the asteroid rushes towards Earth at breakneck of nearly 13kms or more than 29,000mph.

Scientists estimate the monstrous asteroid ranges anywhere from 21 to 52-metres in diameter.

The latest orbital data collected by shows EB4 is on a path which will skim past Earth in the early morning hours of Friday, March 16.

According to NASA’s close approach data, EB4 will arrive around 5.59am UTC.

EB4 is expected to pass the planet within 1.5 lunar distances or 577,500.9 km. This means the asteroid will approach almost as close as the moon.

Thankfully there appears to be no threat of immediate danger and the asteroid will swing past Earth without contact.

In fact EB4 has a rating of -5.94 on NASA’s Palermo Technical Impact Hazard Scale. Palermo Scales below -2 indicate events with “no likely consequences”.

EB4 has not even made it onto NASA’s list of Potentially Hazardous Asteroids (PHAs).

are categorised as PHAs if they are bigger than 100m in diameter and run the risk of coming closer to Earth than than 0.05 AU, or 7,479,894 km.

The US space agency explained: “Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth.

“Specifically, all asteroids with an Earth Minimum Orbit Intersection Distance (MOID) of 0.05 au or less and an absolute magnitude (H) of 22.0 or less are considered PHAs.

“In other words, asteroids that can’t get any closer to the Earth (i.e., MOID) than 0.05 au (roughly 7,480,000 km or 4,650,000 mi) or are smaller than about 140 m (~500 ft) in diameter (i.e., H = 22.0 with assumed albedo of 14%) are not considered PHAs.”

The reality of the matter is that these asteroid approaches are actually very common and hundreds of tonnes of debris crash into Earth every single day.

In fact between now and the end of March another seven notable asteroids will swing by the planet.

Thereafter another nine asteroids will zoom past Earth in May.

NASA said: “Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles.

“About once a year, an automobile-sized asteroid hits Earth’s atmosphere, creates an impressive fireball, and burns up before reaching the surface.

“Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area.

“Only once every few million years, an object large enough to threaten Earth’s civilisation comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences.”

The next asteroid to fly by Earth is Asteroid 2018 EC1, which will show up on Sunday March 18, within 4.4 lunar distances.
