A huge asteroid makes close approach to Earth today

By Trevor Mogg Published April 28, 2022

An asteroid two-and-a-half times the size of the Empire State Building is hurtling toward Earth, but it’s OK to look up.

That’s because it’s been on our radar for decades, giving us plenty of time to calculate its trajectory and confirm that it won’t be colliding with our planet and ending civilization as we know it when it flies by Earth on Tuesday, January 18.

As its name reveals, asteroid (7482) 1994 PC1 was discovered in 1994. It is classified as a “Potentially Hazardous Asteroid” due to its large size (3,280 feet or about 0.6 miles) and proximity to Earth during previous flybys, based on scientists’ calculations.

On Tuesday at 4:51 p.m. ET, the asteroid, traveling at around 43,000 mph (69,200 kph) will come within 1.2 million miles (1.9 million km) of Earth, just over five times the distance between Earth and the moon.

It means that unlike the folks in the hit Netflix movie Don’t Look Up, we have nothing to worry about. And once it’s passed, it won’t be coming back for another 200 years (in the meantime, astronomers will be keeping their eyes peeled for other potentially hazardous asteroids).

One exciting element of the flyby of (7482) 1994 PC1 is that folks with even a basic telescope have a chance of spotting it as it speeds past. EarthSky offers a detailed explanation of where to look and precisely what to look out for as the asteroid makes its close approach.

The possibility of a massive space rock one day hitting Earth is a very real concern that prompted NASA to embark on its DART mission aimed at crashing a spacecraft directly into an asteroid to see if we can alter its path. If the test achieves its objective of altering the course of the asteroid, the system could become a viable way for Earth to protect itself from any hazardous objects spotted heading straight for our planet in the future.

Digital Trends has an article containing everything you need to know about the DART mission, which launched from Vandenberg Space Force Base in California in November 2021.

NASA automated system predicts asteroid impact over Germany

This map shows the location where the small asteroid 2024 BX1 harmlessly impacted Earth’s atmosphere over Germany, about 37 miles (60 kilometers) west of Berlin, on Jan. 21. A NASA system called Scout predicted the impact time and site within 1 second and about 330 feet (100 meters).

Earth is frequently bombarded by small asteroids, which burn up harmlessly in the atmosphere. However, identifying and tracking these asteroids is an important step in protecting the Earth against the threat of larger and potentially more dangerous impacts. NASA recently predicted the impact of a small asteroid that struck Germany using its impact prediction system, Scout.

"A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET)," NASA wrote in an update. "At 95 minutes before it impacted Earth’s atmosphere, NASA’s Scout impact hazard assessment system, which monitors data on potential asteroid discoveries, gave advance warning as to where and when the asteroid would impact. This is the eighth time in history that a small Earth-bound asteroid has been detected while still in space, before entering and disintegrating in our atmosphere."

NASA cracks open its first sample from an asteroid, foiling two sticky screws

NASA’s OSIRIS-REx curation engineer, Neftali Hernandez, attaches one of the tools developed to help remove two final fasteners that prohibited complete disassembly of the TAGSAM (Touch-and-Go Sample Acquisition Mechanism) head that holds the remainder of material collected from asteroid Bennu. Engineers on the team, based at NASA’s Johnson Space Center in Houston, developed new tools that freed the fasteners on Jan. 10.

NASA returned its first sample of an asteroid to Earth last year, landing a sample collected from asteroid Bennu in the Utah desert in September. Researchers were able to extract 70 grams of material from the canister that had been carried back to Earth by the OSIRIS-REx spacecraft, making this the largest asteroid sample ever brought to Earth. The scientists involved knew there was more material inside the mechanism, but getting at it proved difficult -- until now, as NASA has announced it has now managed to open up the troublesome mechanism.

You might think it would be an easy job to unscrew a canister and dump out the material inside, but extraction was a lengthy and technical process. That's because the focus was on preserving as much of the precious sample as possible, trying not to let any of the particles get lost. The issue was with two of the 25 fasteners that held the sample inside the collection mechanism. The mechanism is kept inside a glove box to prevent any loss, and there were only certain tools available that worked with the glove box. So when the fasteners wouldn't open with the tools they had, the team couldn't just go at them with any other tool.

NASA’s Lucy spacecraft will soon make its first flyby of an asteroid

An artist's concept of the Lucy Mission.

NASA's Lucy spacecraft, which launched in 2021, is on its way to the orbit of Jupiter to study the Trojan asteroids there. It won't arrive there until 2027, but the spacecraft will have the opportunity to do some extra science before then, as it will soon be making a flyby of another asteroid called Dinkinesh. At less than half a mile wide, this small asteroid sits in the main asteroid belt between Mars and Jupiter, and it will be Lucy's first asteroid flyby.
