After taking another peek at the "city-killer" asteroid that once had a small but uncomfortable chance of smashing into our planet, astronomers have figured out what it actually looks like: a flat, spinning disk. The preferred analogy has been to compare the shape to a hockey puck. To us, this sounds like a huge missed opportunity to say that the Earth was — however briefly — under threat by a literal flying saucer, just like in that one movie. The findings come from a preprint study, accepted

A newly discovered asteroid is on track for a close brush with Earth—and it might even slam into the Moon. Recently, astronomers got a closer look at the giant space rock, revealing its violent origin story. Using the Keck Observatory on Maunakea, Hawaiʻi Island, a team of astronomers was able to identify the physical properties of asteroid 2024 YR4 and uncover its potential origin. The menacing asteroid may have broken off from a larger space rock following a collision. It also likely originat

That "city-killer" asteroid may no longer be projected to strike Earth any time soon, but scientists are still keeping close tabs on it. Using the mighty James Webb Space Telescope, astronomers have imaged the once-menacing space rock, dubbed 2024 YR4, in infrared light, providing our best estimate yet of its true size. It's also a convincing demonstration of the telescope's usefulness in assessing the hazards of near-Earth asteroids in the future. Previously, our ground-based glances at 2024

Remember the potential "city killer" asteroid we were all freaking out about, 2024 YR4? Initially predicted with a small but unsettling chance of hitting our planet seven years from now, astronomers eventually ruled out that apocalyptic outcome once they were able to get better observations. But the saga's not over. 2024 YR4 will be back for another pass, Athabasca University astronomer Martin Connors writes in an essay for The Conversation — and there'll be others like it. As Connors explains

Whew. Earth has dodged an asteroid scare. Asteroid 2024 YR4 was looming large in humanity's vision. At one point, it was calculated to have a roughly 3.1% chance of impacting Earth on Dec. 22, 2032. That was enough to trigger some concern, but astronomers cautioned that more data was needed to fully understand the asteroid's trajectory and size. The new data is in. "NASA has significantly lowered the risk of near-Earth asteroid 2024 YR4 as an impact threat to Earth for the foreseeable future,"

It was only a few days ago that a certain fear-mongering website named, ahem, Ars Technica published an article about the prospect of a killer asteroid striking the planet Earth in the year 2032. At the time, the odds of a small asteroid first discovered late last year—and designated 2024 YR4—hitting us were non-negligible. There was an estimated 3.2 percent chance that the large rock would impact the planet eight years from now. In the days since then, the odds have fallen dramatically. Based

It's not great news, but don't panic: Astronomers spotted an asteroid that has a roughly 3.1% chance of impacting Earth on Dec. 22, 2032. Space agencies are monitoring the newly discovered asteroid and still learning more about its size and path, so don't mark your calendar for doomsday just yet. Although the odds of the asteroid hitting Earth have increased recently, that number is not set in stone. There's still a lot to learn about the space rock. Designated 2024 YR4, the asteroid was first
