⭐️#NASA's #asteroid deflection test that saw it intentionally crash a #spacecraft into a space rock was a SUCCESS – shaving 33 minutes off the rock's orbit…
1. The #US #space agency's refrigerator-sized satellite managed to shave 33 minutes off the orbit of a 520ft-wide (160m) asteroid known as Dimorphos when it careered into it at 14,000mph (22,000km/h) in September last year.
2. That is nearly five times greater than predicted and more than 25 times the change in orbital period required for the mission to be considered a success.
Dimorphos orbits a much larger 2,550ft-wide (780m) object called Didymos 6.8 million miles from #Earth.

🚨ATTENTION! A small asteroid is expected to safely impact the French-English channel in ~4 hours time, 03:00:03 UT tomorrow. Object size is around ~1 meter and should appear as bright as the Moon momentarily as it enters the atmosphere. Approx visibility circle posted below. 1/
Object was discovered by the Konkoly Observatory in Hungary a few hours ago. Temporary designation of the object is Sar2667. It is expected to enter the atmosphere at around a 45° angle, coming from the East. 2/
Impact time of 03:00:03 has an uncertainty of a few minutes as it stands, but should be narrowed down to a few seconds by impact time. I'll keep it updated here in this thread. 3/

A 1-meter meteoroid (small #asteroid) has been detected and is expected to *safely* strike Earth's atmosphere over northern France between 3:50-4:03 CET.

In the area? Look out for a #ShootingStar!☄️

This is just the seventh time an #asteroidimpact has ever been predicted before it happens - a sign of the rapid advancements in global asteroid detection capabilities!


📸This was the 6th

Last estimation shows #Sar2667's point of impact getting much closer to the #Rouen area.

Safe #AsteroidImpact

A <1m object has struck🌍in the skies above Niagara Falls, becoming a safe #fireball. For just the 6th time, global #asteroid warning systems saw it pre impact, alerting #PlanetaryDefence experts where & when. 'Only' 6x, but this capability is rapidly improving

Even, observations of the object before it struck!

"Then the third angel sounded: And a great
star fell from heaven, burning like a torch,
and it fell on a third of the rivers and on the
springs of water. The name of the star is
Wormwood. ImageImageImage
A third of the waters became
wormwood, and many men died from the
water. because It was made bitter.

The prestigious international journal @Nature has expanded its scope beyond science and is now publishing papers in the field of Biblical archaeology. A paper published today asks the question "Did God smite the sinners of Sodom with an #asteroid?"…
I just skimmed through the paper and see that my model of asteroid airbursts is cited as the mechanism by which God smote this evil city. Here's a screenshot of the paper's Figure 53, which shows a cross-section of a fire-and-brimstone event I simulated. Image
It must sound like I'm making this up, especially if you recall my April Fool's joke claiming that the Alabama legislature proclaimed that the value of pi is exactly 3 (see…). But this is Biblical archeology, not Biblical math, & so within @Nature's scope.

The biggest #asteroid of 2021 is going to zoom past Earth tonight flying as fast as 100,000 kmph - By @pabsgill…
The biggest asteroid of the year is set to fly past Earth tonight. The space rock, dubbed 2001 FO32, is nearly half a kilometre wide — that’s more than twice the height of India’s Statue of Unity, the tallest statue in the world.
Moreover, it will be closing in on the planet at a whopping speed of 123,876 kilometres per hour (kmph), which is faster than an average asteroid.

Two Asteroids of Over 19 Metre Diameter to Fly Past Earth This Tuesday; One to Approach Closer to #Earth Than #Moon - by @deekshith_np…

(📸: NASA/JPL-Caltech) Image
Two #asteroids with an estimated diameter between 19 and 49 metres will pass by Earth on Tuesday, September 1. While both of them are relatively large, only one of them will be very close to Earth in terms of astronomical distances.
Both asteroids, officially named #2011ES4 and #2020QG5, are classified as near-Earth objects but are not expected to pose any harm to Earth on their approach.

No other #asteroid is going to get closer to #Earth in the next decade than the one set to fly by on September 1 - by @pabsgill… Image
Many #asteroids come and go but most keep their distance from Earth as they fly past. Now one daring #asteroid is set to come closer to the planet — closer than even the #Moon on September 1.
Officially recognized as #Asteroid11ES4, the space rock will be a mere 121,000 kilometers (kms) from #Earth as it shoots past the planet next week. The #moon, on the other hand, is three times further away at 384,400 kms.

A car-sized #asteroid flew within 1,830 miles of #Earth over the weekend — the closest pass ever — and we didn't see it coming…
A car-sized #asteroid flew within about 1,830 miles (2,950 kilometers) of #Earth on Sunday.
That's a remarkably close shave — the closest ever recorded, in fact, according to asteroid trackers and a catalog compiled by Sormano Astronomical Observatory in Italy.

We continue our #AsteroidDay content and, looking to the future, Prof of Planetary and Space Science, Simon Green is working on space missions that will visit asteroids in coming years.

Why? For planetary defence - how we protect Earth from impact by space rocks in the future.
One of the planetary defence missions is @NASA's DART and the other is @esa’s HERA, both looking at how to deflect asteroids on a collision course with Earth. @ESA have a great video narrated by @DrBrianMay all about how these missions are connected.
For the research side, you can check out Prof Simon Green’s research about the science behind DART and HERA for asteroid deflection.

Today we’re posting asteroid content to celebrate #AsteroidDay.

In case you missed it this morning, @ESA made a programme as part of @AsteroidDay, which included @StarkeyStardust as a guest. It’s a good place to start on your @AsteroidDay journey.

Another key aspect of asteroid science is in figuring out the danger they pose to life on Earth. The poor dinosaurs owe their demise to a large space rock colliding with our planet but in this article, @monicaGrady discusses what small asteroids could do.…
Asteroids that pose a risk to Earth are 'near-Earth asteroids' - those objects that are close to our planet. This video includes Prof of Planetary and Space Science, Simon Green, speaking about them after @ajnorton3 talks about ‘A Clockwork Universe’.

To mark #AsteroidDay, we’ve got a whole day of #asteroid content ready for you. Stay on board to learn how and why we study asteroids with spacecraft, and how we protect Earth from them colliding with us. We'll even look at #SpaceMining!
#AsteroidDay was founded by astrophysicist @DrBrianMay, Astronaut Rusty Schweickart Filmmaker @GrigRichters; and B612 President Danica Remy, to encourage the public and governments to learn more about asteroids and the role they play in our Solar System.
#AsteroidDay marks the anniversary of the largest asteroid impact in recorded history, Tunguska, 1908. Such impacts are part of the reason scientists study asteroids, working on resources to search for and deflect asteroids from Earth-crossing orbits.
