A "potentially hazardous" pyramid-size asteroid is about to zoom past Earth at around 48,000 mph (77,300 km/h) this week as it reaches its closest point to our planet in more than 100 years. But the hefty space rock poses zero risk of hitting us now or in the future, data shows. @LiveScience

Eight observing stations in Poland and Germany observed successfully the stellar occultation by asteroid (88) Thisbe on 2025 March 19.

The chords are well placed across the shadow profile and confirm the DAMIT 3-D model 149. The profile measures 231 x 191 km.

Good work of the observers and the evaluation team of SODIS!

Hat noch wer heute Abend im Raum #Oldenburg oder sogar in #Norddeutschland dieses Phänomen am #Himmel gesehen? Sah aus wie ein #Komet, bewegte sich west-/nordwestlicher Richtung aber langsam gen Horizont. Ist da irgendwas verglüht, wenn ja, was? Konnte bisher keine Infos dazu finden.

Gerne boosten.

#Astronomers discover 196-foot #asteroid with 1-in-83 chance of hitting #Earth in #2032
"Impact probability is still very low, and the most likely outcome will be a close approaching rock that misses us."
Such an impact could cause an explosion in the atmosphere, called an "airburst," or could cause an impact crater when it slams into the ground. This is enough to see asteroid #2024YR4 leap to the top of the #ESA's #NEO impact Risk List and #NASA's Sentry Risk Table.

Lurking Inside an Asteroid: Life’s Ingredients
Scientists studying samples that #NASA collected from #asteroid #Bennu found a wide assortment of organic molecules that shed light on how life arose. The chemistry that produced them might be going on today on the ice moons of #Jupiter and #Saturn.
“Our odds of finding life elsewhere are increasing,” said Daniel Glavin, a senior scientist for sample return at NASA’s Goddard Space Flight Center

Why do the odds of asteroids hitting Earth keep fluctuating?

@Salon explores the question with astronomy professor Richard P. Binzel: https://flip.it/0.AJBW

This is doubly good news (a) the #asteroid won’t hit Earth in 2032 and (b) there’s now a 1 in 59 chance it’ll hit the Moon and we’ll get to see a new crater being made. Plus maybe a few small meteor showers a while later?

2024 YR4 asteroid impact update!

New observations of 2024 YR4 conducted with ESO’s Very Large Telescope and facilities around the world have all but ruled out an impact of the #asteroid with our planet. The asteroid has been closely monitored in the past couple of months as its odds of impacting Earth in 2032 rose to around 3%, the highest impact probability ever reached for a sizable asteroid. After the latest observations, the odds of impact dropped to nearly zero.

The odds that asteroid 2024 YR4 would hit Earth in 2032 rose and then plummeted in recent days. The latter is good news, considering the asteroid is thought to have the potential to release 500 times more energy than the atomic bomb that destroyed Hiroshima. However, riskier asteroids may continue to pester our planet. Read more from @LiveScience:

NASA massively lowers impact risk of 'city-killer' asteroid 2024 YR4 to 1 in 360

https://www.space.com/asteroid-2024yt4-impact-risk-drop-nasa

> Don't worry. Asteroid 2024 YR4 now has a 99.72% chance of missing Earth in 2032.

Odds of asteroid YR4 hitting Earth just went up again. This time to 3.1%, reaching new high

This is where rooting for the underdog really matters.
