2029 close approach The closest known approach of Apophis occurs at April 13, 2029 21:46 UT, when Apophis will pass Earth closer than geosynchronous communication satellites, but will come no closer than 31,600 kilometres (19,600 mi) above Earth's surface. wikipedia.org99942 Apophis

Asteroid Bennu now has a greater chance of hitting Earth through 2300, but still slim

But don’t spiral just yet: Scientists reported that the odds are still low that Bennu will hit us in the next century.

“We shouldn’t be worried about it too much,” said Davide Farnocchia, a scientist with NASA’s Center for Near Earth Object Studies at the Jet Propulsion Laboratory in Pasadena, California, who served as the study’s lead author.

The chances of the asteroid clobbering into Earth have risen from 1-in-2,700 to 1-in-1,750 over the next century or two. But scientists now have a much better idea of Bennu’s path because of data gathered by NASA’s Osiris-Rex spacecraft. “So I think that overall, the situation has improved,” he added.

Osiris-Rex is currently headed back to Earth after collecting samples from Bennu – which is considered one of the two most hazardous known asteroids in our solar system. The samples will arrive in 2023 and will help scientists in predicting the asteroid’s orbital path.

Bennu will have a close run-in with Earth in 2135 when it passes within half the distance of the moon. Earth’s gravity could alter its future path and put it on a collision course with Earth in the 2200s. But this is less likely now based on Osiris-Rex findings.

If Bennu did come crashing down into Earth, NASA maintains that it wouldn’t wipe out life dinosaur-style, but rather create a crater around 10 to 20 times the size of the asteroid. The area of devastation would be 100 times the size of the crater.

According to Lindley Johnson, NASA's planetary defense officer, scientists are already ahead of the curve with Bennu, which was discovered in 1999. This increases the chances of pushing them out of Earth’s orbit.

“One hundred years from now, who knows what the technology is going to be?” he said.

In November, NASA plans to launch a mission to knock an asteroid off-course by hitting it. The experimental target will be the moonlet of a bigger space rock.

Elsewhere, NASA is currently looking for people to spend a year pretending to live on Mars in the name of science. If that seems like something you’d be interested in, applications are now open.

Date found for mile-wide asteroid's highest chance of hitting Earth

TweakTown 12 August, 2021 - 03:31am

According to a new study published in the journal Icarus, researchers used data acquired by NASA's OSIRIS-REx spacecraft to measure the trajectory of the mile-wide asteroid named Bennu. Bennu has been orbiting the Sun for hundreds of millions of years, but according to researchers' highly accurate estimations, Bennu has a chance of colliding with Earth in the somewhat relative future.

The researchers calculated Bennu's trajectory and found that there is a 1-in-750 chance that the asteroid will collide with Earth over the next 300 years, which was a much higher probability than researchers previously estimated. The scientists also found that all of the closest encounters with Bennu will happen during the late 2200s and the early 2300s. Additionally, the researchers managed to boil the data down to a single date - September 24, 2182. During the afternoon on that day is the single likeliest time for impact as Bennu has a 1-in-2,700 chance of hitting Earth.
