"Asteroid Apophis Is Coming Back And NASA Has a Risky Plan" https://youtu.be/hxy_Z6qp59g

So apparently in 2029 Apophis will be closer to Earth than satellites. The asteroid that wiped out the dinosaurs was 10-15km across, Apophis is 300m. So not a world ending event but a devastating event for sure.

That is why NASA has been experimenting with moving the trajectory of asteroids. They have a few years left to prepare still.

GROUND-BASED IMAGES OF #ASTEROID #STRIKE: Yesterday, NASA's DART spacecraft hit asteroid Dimorphos--an incredible, dramatic bullseye 11 million kilometers from Earth. Surprising even NASA, ground-based telescopes had no trouble seeing the impact. Astronomers with the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii recorded a bright cloud of debris:

This was the result of the 1,340-pound spacecraft plunging into Dimorphos at 14,000 mph. Most of the debris is probably asteroid dust, but some of DART may be in there, too. A similar video was recorded by the 1-meter Lesedi telescope in South Africa.

Mission scientsts say DART hit the asteroid less than 17 meters off center. Think about that: 17 meters off at a distance of 11 million kilometers. NASA still has the right stuff.

Now that the dust has cleared, astronomers are monitoring #Dimorphos's #orbit to find out whether or not it has changed in response to the strike. Even a slight shift would prove that human tech can alter an asteroid's trajectory--a possible strategy for future Planetary Defense.
