The asteroid managed to get within just 73,000 kilometers of our planet without anyone noticing. The miss lends a new sense of urgency to preparations for a potential collision one day.

The news: On Thursday July 25 an asteroid dubbed “Asteroid 2019 OK”, measuring 57 to 130 meters wide (187 to 427 feet), got uncomfortably close to Earth, according to NASA’s near-Earth objects database. It was less than one-fifth of the distance to the moon away, making it a very close call in space terms. If it had landed on a populated area it could have caused major damage, although this outcome is statistically quite unlikely.

Should we worry? It’s hard not to feel concerned that a “city-killer” sized asteroid wasn’t detected further ahead of time. It was announced just hours before it passed by Earth, after being detected just a few days beforehand by teams in the US and Brazil. Its relatively small size, unusual orbit, and fast speed all conspired to make it tough to spot, researchers told the Washington Post.

A killer asteroid will hit the Earth, and it is not a matter of “if” but “when,” based on the discussions during last week’s 2019 International Planetary Defense Conference.

Bill Nye opened up about the threat of asteroid impacts and possible extinction, explaining that people need to be more aware of this threat. “The Earth is going to get hit with another asteroid,” Nye said during the 2019 International Planetary Defense Conference. “The problem is, we don’t know when.”

Nye, who is known as the TV “Science Guy” and is currently the CEO of the Planetary Society, continued by saying that even if an asteroid doesn’t hit Earth within the next few decades, the threat is still there.

In 2022, if all goes well, NASA will launch Psyche, a space probe intended to visit the asteroid of the same name (16 Psyche is its formal designation). It’s a particularly exciting mission given Psyche’s unique nature and highly unusual composition.

The asteroid belt is composed of three types of asteroid: C-type (carbonaceous, ~75 percent of all asteroids), S-type (silicate-rich, ~17 percent of asteroids) and M-type (metal-rich), which are roughly 10 percent of the total population. The numbers, in this case, don’t add up to 100 percent because we aren’t sure of the exact ratios. 16 Psyche is an M-type asteroid made of iron-nickel. What makes it unusual is that it’s believed to be the now-exposed core of a protoplanet. It’s also estimated to be worth $10,000 quadrillion dollars, if anybody has a towing hitch handy.

Unusual Trajectory

The new research hasn’t yet been published, but it’s available on the preprint server ArXiv as of Monday. In it, Harvard astronomer Avi Loeb — the same dude who doubled down on the idea that ‘Oumuamua could be an alien spacecraft — suggests that a three-foot-wide interstellar meteor flew over Papa New Guinea’s Manus Island before crashing down.

Because of the meteor’s high speed and particular trajectory past Earth, Loeb and his student Amir Suraj suggest that it couldn’t have been bound in an orbit about the Sun. Rather, they argue, it might have come from somewhere beyond our solar system.

Astronomers claim detection of a first observed interstellar meteor; one that collided with Earth’s atmosphere at very high velocity in 2014, somewhere off the coast of Papua New Guinea.

Fossils uncovered in North Dakota appear to preserve the catastrophic fallout of the asteroid impact that wiped out the dinosaurs–but experts remain cautious.

The asteroid, dubbed by NASA Asteroid 2019 CB2, is barreling towards a so-called “Earth Close Approach”. NASA’s scientists have pinpointed the asteroid’s passage down to 1.20am GMT (UTC) on Sunday, February 10. The incredible flyby comes just five days after NASA’s Jet Propulsion Laboratory (JPL) first observed the rock on February 2. As it zips by, Asteroid CB2 will breach speeds of nearly 29,125mph or 13.02km per second.

Not as easy as the movies show. Say it isn’t so.

Incoming asteroids may be harder to break than scientists previously thought, finds a Johns Hopkins study that used a new understanding of rock fracture and a new computer modeling method to simulate asteroid collisions.

The findings, to be published in the March 15 print issue of Icarus, can aid in the creation of asteroid impact and deflection strategies, increase understanding of solar system formation, and help design asteroid mining efforts.

The space rock, dubbed 2013 MD8 will make a ‘close approach’ to our planet tomorrow afternoon.
