The asteroid named 2014 SD224 will enter a range of 0.02019 astronomical units from the Earth’s surface, which is nearly 1.9 million miles.
The diameter of the 2014 SD224 is between 302 and 690 feet (92 to 210 meters), which means it may be more than twice the Statue of Liberty (305 feet) or larger than Salisbury Cathedral (404 feet) .
When the 2014 SD224 flies over the earth, it will travel at a speed of 10 kilometers per second or more than 22,000 miles per hour-approximately 30 times the speed of sound.
Although this asteroid is eight times taller than the Moon, it is still classified as a Near-Earth Object (NEO) and is tracked by NASA.
The asteroid may be more than twice the size of the Statue of Liberty (305 feet) or the Elizabeth Tower (renamed Big Ben) and larger than Salisbury Cathedral (404 feet).

Different types of space rocks
One Asteroid It is a large piece of rock left over from a collision or early solar system. Most are located between the main belt Mars and Jupiter.
A kind comet It is a rock covered with ice, methane and other compounds. Their orbits move them further away from the solar system.
A kind meteor When the debris burns, astronomers call it a flash in the atmosphere.
This fragment itself is called Meteoroid. Most are too small, they evaporate in the atmosphere.
If any meteoroid reaches the earth, it is called Meteorite.
Meteors, meteoroids and meteorites usually originate from asteroids and comets.
Although 2014 SD224-this can be Track on the NASA website -1.9 million miles apart, which is relatively close from an astronomical point of view.
Therefore, NEO defines 2014 SD224, although it will not cause damage.
A near-Earth object is an asteroid or comet whose orbit brings it into or through an area between about 91 million to 121 million miles (195 million kilometers) from the sun, which means it can orbit about 3000 Pass within ten thousand miles (50 million kilometers).
If the width of the object is greater than 460 feet (140 meters), it is considered a potentially hazardous object (PHO).
NASA said: “Near-Earth objects are comets and asteroids. They are attracted by the gravitational force of nearby planets and enter orbit, allowing them to enter the vicinity of the Earth.”
“Comets, mainly composed of water ice and embedded dust particles, originally formed in the cold outer planetary system, while most rock asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.
“The scientific interest in comets and asteroids is largely due to their status, because they are relatively unchanging debris from the formation of the solar system about 4.6 billion years ago.”
according to Publicly available NASA dataAs of Tuesday, 24,629 NEOs have been discovered.
It is estimated that there are approximately 25,000 Near-Earth Objects (NEO) larger than 460 feet (140 meters).
An estimated 1,000 NEOs are larger than 3,280 feet (one kilometer), highlighting the need to track these space rocks.
According to NASA’s “Near-Earth Object Program”, on average, the Earth will be hit by rocks the size of a football field every 5,000 years, and civilization will be hit by asteroids impacted by civilization every 1 million years.

“By constantly searching for asteroids, we hope that over time we will eventually find most of the 100-meter-class asteroids, because every asteroid may pass through our planet many years or decades before it may have a potential impact. ,” NASA Director Paul Chodas said.Near Earth Research Center told Weekly newspaper.
“We have counted more than 95% of true asteroids (1 km or 0.62 miles or more in size), and we know that none of them will be affected in the next century.”
Last month, someone revealed Asteroid the size of a London bus On Friday the 13th, I missed the earth at only 240 miles (386 kilometers)
The space rock is called “2020 VT4”, and it was discovered by the final warning system of the asteroid ground impact on the Mauna Loa River only 15 hours later. Hawaii.
If the distance is closer, the 16 to 33 feet (5 to 10 meters) wide body will burn in the atmosphere of the South Pacific.
Its orbit makes it the same distance from the Earth as the International Space Station, making it the closest asteroid to Earth on record.
Astronomers are looking for asteroids larger than 450 feet because they can cause “catastrophic damage”
Researchers have found most asteroids, which are about one kilometer in size, but are now looking for asteroids about 459 feet (140 m) in size-because they can cause catastrophic damage.
Although no one knows when the next major impact will occur, scientists find themselves under pressure to predict and intercept its arrival.

Rolf Densing, head of the European Space Operations Center (ESOC) in Darmstadt, said: “Sooner or later, we will all be affected by…”
He said that this may not happen in our lifetime, but “the risk of the earth being hit by a devastating event one day is very high.”
“At present, there is nothing we can do.”
