The asteroid that once had a small chance of striking Earth and now might slam into the moon resembles a spinning hockey puck, scientists said Tuesday.
A team of astronomers used the Gemini South Observatory in Chile to observe asteroid 2024 YR4 in multiple wavelengths as it zoomed away from Earth in February, barely 1 1/2 months after its discovery. They created a 3D image of it based on their findings, The Associated Press reported.
The nearly 200 foot (60-meter) asteroid looks more like a flat disk — or not-quite-round hockey puck — than a potato. It also has a rapid rotation rate of about once every 20 minutes.
“This find was rather unexpected since most asteroids are thought to be shaped like potatoes or toy tops rather than flat disks,” the research team lead, Bryce Bolin from Eureka Scientific said in a statement.
Scientists said it most likely originated in the main asteroid belt between Mars and Jupiter, and is rich in silicates.
At one point earlier this year, NASA and the European Space Agency put the odds of the asteroid striking Earth in 2032 at 3%. It's now down to virtually zero for the next century, but there's a 3.8% chance it could strike the moon instead. Even if that happens, NASA assures the moon's orbit will not be altered.
The asteroid —- which swings our way every four years — will be too far away by next week for ground telescopes to see. The Webb Space Telescope will take another look later this month or next.
Scientists consider all this good practice for when a potentially killer asteroid heads our way.

Nearly 1,000 firefighters and helicopters battled a wildfire about 40 kilometers (25 miles) northwest of France's second-largest city Marseille on Friday, but officials said lower temperatures and increased humidity had improved the situation.

The 240-hectare (593 acres) wildfire flared up a week after a separate conflagration reached the northwestern outskirts of Marseille, forcing people to evacuate or into lockdown and temporarily shuttering the area's airport.

Pierre Bepoix, the colonel of rescue operations and deputy director for the area's firefighters, said 150 people had been evacuated, but firefighters had managed to save 150 homes and portions of the area's forests.

"It was a fire that swept through relatively dense vegetation ... which made our work particularly complicated," Bepoix told Reuters. "Obviously, priority was given to the preservation and protection of these homes and the lives that could be in these buildings."

Local officials said in a statement that 120 homes had been threatened by the fire, adding that it was not possible yet to identify any possible damage to them, and that two firefighters had been injured.

Meanwhile in Spain, a wildfire that broke out on Thursday evening in the central Toledo province and could be seen from downtown Madrid, ravaged 3,200 hectares of woodland.

Regional emergency services said early on Friday firefighters had secured the perimeter, though there were concerns over strong winds and high temperatures forecast throughout the day.
