Astronomer David Smith captured video footage of an enormous asteroid that measured 3,451 feet across as it came closest to Earth in just 90 years.

The asteroid number 7482 (1994 PC1) can be described as a tiny white dot that traveled towards our planet on Monday, January 17, at 19:00 GMT. 

The following evening, at 21:51 GMT (16:51 EST) on January 18, the asteroid made its closest approach to Earth since 1933, coming within 1.2 million miles of our planet. 

The clip was captured by Gianluca Masi, an astrophysicist and manager of the Virtual Telescope Project, provided by the Bellatrix Astronomical Observatory in Italy. 

Another eight so-called near-Earth objects (NEOs) are set to pass safely by Earth this month, according to NASA.  

This image, a still from the footage, comes from a single, 60-second exposure, remotely taken with the 'Elena' robotic unit available at Virtual Telescope

ASTEROID 7582 (1994 PC1)

In 1994, the first discovery of space rock 7482 (94 PC1) occurred.

RH McNaught, who used the Siding observatory to find it in Australia, was able to spot it.

The Sun orbits it every 572 day, but the orbit is eccentric and takes it to approximately 0.9 to 1.5 AU. 

One AU represents the distance between Earth’s surface and Sun’s. 

It was only 699,000 kilometers from Earth when the last recorded approach was made in 1933. 

Masi said that they captured many images of the dangerous (7482) 1994 PC1 asteroid while it was safely near them. 

“We made nice animations and a static picture. This image was taken remotely with an Elena robotic unit at Virtual Telescope. It took 60 seconds to capture the exposure. 

The telescope recorded the rapid apparent motion of the asteroids, which is the reason stars appear to have long trails. However, the asteroid appears like an sharp spot of light at the centre of the picture, with an arrow marking it. 

“Using all of the images in the sequence, we were able to create the animation below showing 1994 PC1 motion against the stars. 

NASA has put the diameter of the asteroid (7482) (1994 PC1) at 3,451 feet (1.052km). This is much higher than what the Burj Khalifa, Dubai’s tallest building, is 2,722 feet high.  

Following its close approach on Tuesday, 7482 (1994 PC1) won’t be this close to Earth again until the year 2105, according to NASA JPL-Caltech’s Solar System Dynamics.     

Asteroid number 7482 (1994 P1) orbits the sun approximately every 1.5 years. It was discovered for the first time by RH McNaught, an astronomer who used the Siding Spring Observatory, New South Wales. 

Asteroid 7482 (1994 PC1) was first discovered by Australian astronomers in 1994 and made a close approach of Earth this week

Asteroid #7482 (1994 P1) was the first to be discovered by Australian astronomers. This asteroid made a very close approach to Earth on this week of April 22, 1994.

NASA puts the diameter of asteroid 7482 (1994 PC1) as 3,451 feet (1.052km), much larger than the tallest building on Earth

NASA estimates that the diameter (1.052km) of Asteroid 7482 (1994 P1) is 3,451ft, which is more than any tall building.

According to Astronomers, its orbit ranges from 0.9 to 1.8AU. 1AU refers to the distance between Earth and sun. 

It’s a S-type common stony asteroid. Every close encounter gives astronomers the opportunity to examine the surface and discover more about these old space rocks. 

NASA and various agencies monitor more than 28,000 known asteroids while they orbit the Sun.

The massive asteroid, more than twice the size of the Empire State Building in New York, came within 1.2 million miles of the Earth

The following are some examples asteroid This is large piece of rock leftover from early Solar System collisions. They are found between Mars and Jupiter within the Main Belt.

Comet Is a rock that has been covered with methane, ice and other compounds. Their orbits lead them further from the Solar System.

Meteor It is what Astronomers refer to when there is a flash in the atmosphere caused by debris burning up.

The debris is also known as “a” meteoroid. Many of them are small enough to be vapourized in the atmosphere.

It is called “a meteoroid” if it reaches Earth. Meteorite.

Asteroids and comets are the usual sources of meteoroids, meteoroids, and meteorites.

NASA claims that none of the asteroids known to have collided with Earth in the immediate future. However, there are other asteroids whose orbits are unknown.  

Asteroids and other space objects are being monitored by NASA’s Center for Near Earth Object Studies. 

It describes 7482 (1994PC1) as an near-Earth object, (NEO), and potentially dangerous asteroid (PHA). 

NEOs are an asteroid or comet whose orbit brings it into or through a zone between approximately 91 million and 121 million miles (195 million km) from the Sun, meaning that it can pass within about 30 million miles (50 million km) of Earth’s orbit. 

It is considered potentially hazardous if the object measures more than 460ft (140m) in diameter. 

‘NEOs are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighbourhood,’ said NASA.

Composed of mostly water ice, embedded dust particles and other elements, comets were originally created in the outer planetary systems. Most of the rocky asteroids formed between Jupiter and Mars in the inner solar system. 

“The reason that comets are still of scientific importance is their role as relatively unaltered remnants of the solar system’s formation around 4.6 billion years ago. 

NASA publicly accessible data shows that 27,948 NEOs were discovered as of Tuesday.   

The space rock, called 7482 (1994 PC1), poses no threat to the Earth as it will be five times further away from the planet than the Moon, as it shoots by at 43,000 mph (pictured, an artist's impression of an asteroid)

The Earth is safe from the space rock, 7482 (1994PC1)), as it travels at 43,000 mph, which is five times faster than the Moon.

Asteroid 7482 (1994 PC1) orbits the Sun every 1.5 years. Its orbit is depicted here in relation to the planets in our Solar System

Every 1.5 years, Asteroid Number 7482 (1994 PPC1) orbits around the Sun. This is its orbit in relation to other planets of the Solar System.

There are approximately 25,000 Near-Earth Objects (NEOs), which can be larger than 460 feet (135 metres).

Additionally, there are approximately 1,000 NEOs that exceed 3280 feet (1 km), which shows the importance to track these space rocks.

NASA data shows that eight additional NEOs will be passing Earth between January 20-28. 

One of these, Asteroid 2022 AB, could be up to 361 feet wide, which is not much in comparison to asteroid 7482 (1994 PC1) but still larger than Big Ben.

NASA’s Near-Earth Object Program estimates that Earth is struck by a small rock about the size of a football every 5,000 to a million years.      

NASA created a program for planetary defense to combat the danger posed by asteroids. It includes DART (double asteroid redirection test) which was launched in November. 


Experts believe that it could take multiple impacts of a large human-made device to deflect an asteroid like Bennu. It has a very small chance of striking Earth within a century.

California scientists have used projectiles to shoot at meteorites in an attempt to mimic the most effective methods for altering the trajectory of an asteroid. 

According to the results so far, an asteroid like Bennu that is rich in carbon could need several small bumps to charge its course.

NASA discovered that Bennu has slightly higher chances of reaching Earth because it is only a third mile in diameter.

The space agency upgraded the risk of Bennu impacting Earth at some point over the next 300 years to one in 1,750.

Bennu also has a one-in-2,700 chance of hitting Earth on the afternoon of September 24, 2182, according to the NASA study.  

Since the 1960s scientists have been trying to prevent an asteroid ever striking Earth. However, previous attempts have tended to involve theories about how to break the cosmic object down into many thousands.

These pieces can potentially be zoomed towards Earth and pose almost the same danger and threat to humanity as original asteroid. 

An alternative approach called “kinetic impacts deflection” is to fire something into space which gently bumps an asteroid out of orbit away from Earth. However, it keeps its integrity intact. 

Recent KID efforts were outlined at the 84th annual meeting of the Meteoritical Society held in Chicago and led by Dr George Flynn, a physicist at State University of New York, Plattsburgh.  

In conversation with The New York Times, Dr Flynn stated that “you might need to use multiple impacts.” ‘It [Bennu]Although you may miss it, just barely is sufficient.

NASA’s Ames Vertical Range has been home to researchers since the Apollo era. It was built at Moffett Federal Airfield, California, Silicon Valley.

The projectiles were small and spherical, hitting meteorites suspended on pieces of nylon string.

The team used 32 meteorites – which are fragments of asteroids that have fallen to Earth from space – that were mostly purchased from private dealers. 

They were able to study the effect of momentum on an object made by humans firing at an asteroid, and not just how it would be destroyed. 

Dr Flynn explained that if you broke it up, some of the pieces could still be in a collision course to Earth. 

Carbonaceous chondrite (C-type) asteroids, such as Bennu, are the most common in the solar system. 

They are darker than other asteroids due to the presence of carbon and are some of the most ancient objects in the solar system – dating back to its birth. 

According to the findings from experiments at AVGR, the type of asteroid being targeted (and how much carbon it has in it) may dictate how much momentum would be directed at it from any human-made KID device.   

Researchers found that C-type meteorites can withstand less than one-sixth as much momentum before they shatter. 

‘[C-type]Experts concluded that asteroids can be more difficult to disperse without disrupting than normal chondrite asteroids.  

“These results suggest that multiple consecutive impacts might be necessary to disrupt rather than deflect asteroids.

Therefore, around 160 years in the future – when Bennu is most likely to collide with Earth, according to NASA – a KID device would have to give it a series of gentle nudges to prevent it from breaking up and sending dangerous splinter fragments flying towards Earth.

NASA’s recent study about Bennu, published in the journal Icarus, did point out there is more than a 99.9 per cent probability Bennu will not smash into Earth over the next three centuries. 

NASA released a statement saying that Bennu, despite the low chances it will hit Earth, remains one of two potentially dangerous asteroids known to our solar system.
