NASA said an asteroid larger than the Statue of Liberty will fly by Earth on Christmas Day

An asteroid larger than the Statue of Liberty will fly past Earth at 8:20 PM GMT on Christmas Day, according to data from NASA. Near Earth Studies Center.

The asteroid, named 2014 SD224, will come within 0.02019 astronomical units, or approximately 1.9 million miles, from Earth’s surface.

The 2014 SD224 is between 302 and 690 feet (92 to 210 meters) in diameter – meaning it could be more than twice the size of the Statue of Liberty (305 feet) or larger than Salisbury Cathedral (404 feet).

Since the 2014 SD224 flies over Earth, it will travel at 10 kilometers per second or more than 22,000 miles per hour – nearly 30 times the speed of sound.

Although it is about eight times farther from the moon, the asteroid is classified as a Near-Earth Object (NEO) and is tracked by the Space Agency.

The asteroid could be more than twice the size of the Statue of Liberty (305 feet) or Elizabeth Tower (known as Big Ben) and larger than Salisbury Cathedral (404 feet)

Different types of space rocks

that asteroid It is a large piece of rock left by collisions or the early solar system. Most of it is located between Mars and Jupiter in the main belt.

a The culprit It is a rock covered with ice, methane and other compounds. Their orbits take them away from the solar system.

a meteor It is what astronomers call a flash of light in the atmosphere when debris is burned.

This debris itself is known as A. meteor. Most of them are so small that they flow into the atmosphere.

If any of this meteorite reaches Earth, it is called a meteor.

Meteors, meteorites and meteorites usually originate from asteroids and comets.

Although 2014 SD224 – which can be Track it down on the NASA website At a distance of 1.9 million miles, this is relatively close astronomically.

For this reason, 2014 SD224 was identified by NEO, although no harm is expected.

A NEO is an asteroid or comet that its orbit brings to or through an area located between about 91 million and 121 million miles (195 million km) from the sun, which means that it can pass within 30 million miles (50 million km) of Earth’s orbit. .

If the object is greater than 460 feet (140 meters), it is considered a Potentially Dangerous Object (PHO).

NASA said: “Near-Earth objects are comets and asteroids pushed by the gravity of nearby planets into orbits that allow them to enter the vicinity of Earth.”

Comets mostly consist of water ice with compact dust particles, and were originally formed in the cold outer planetary system while most of the rocky 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 condition as a relatively unchanged remnant of the formation of the solar system about 4.6 billion years ago.”

to me Publicly available NASA data, 24,629 near-Earth objects had been detected as of Tuesday.

It is estimated that there are about 25,000 NEOs larger than 460 feet (140 meters).

There are also an estimated 1,000 NEOs larger than 3,280 feet (one kilometer), highlighting the need to track these space rocks.

On average, Earth collides with a rock the size of a soccer field every 5,000 years, and an asteroid ends up with civilization every million years, according to NASA’s Near Earth Object Program.

“Through our constant search for asteroids, we would eventually expect to find the majority of asteroids that are 100 meters in size over time, with each occurring on our planet many years or decades before a potential impact,” said Paul Chodas, NASA Administrator. Earth near Newsweek.

We’ve already stripped over 95 percent of really large asteroids (about a kilometer in size or 0.62 miles and larger) and know that none of them have any chance of impact over the next century.

Last month, an asteroid the size of a London bus was detected that missed Earth by 240 miles (386 km) – Friday the 13th.

The space rock, dubbed “ 2020 VT4, ” was detected just 15 hours after its closest approach by the last warning system of Earth’s asteroid in Mauna Loa, Hawaii.

Had it come too close, an object 16 to 33 feet (5 to 10 meters) wide would have burned in the atmosphere over the South Pacific Ocean.

Its orbit put it as close to Earth as the International Space Station, making it the closest asteroid to pass Earth on record so far.

Astronomers are looking for asteroids over 450 feet high because they can cause “catastrophic damage”

Researchers have discovered most asteroids with a size of about 1 km, but are now looking for those around 459 feet (140 meters) – where they can cause catastrophic damage.

Although no one knows when the next big impact will happen, scientists have found themselves under pressure to predict – and intercept – its arrival.

“Sooner or later we will have … little or no effect,” said Rolf Densing, who heads the European Space Operations Center (ESOC) in Darmstadt.

It may not happen in our lifetimes, he said, but “the risk of hitting Earth one day in a devastating event is extremely high.”

“At the moment, there is not much we can do.”
