NASA's latest asteroid warning is about a space rock named 2023 KU that is hurtling towards Earth at a speed of 64,000 kilometres per hour. The 370-foot asteroid belongs to the Apollo group of asteroids and is about the size of a 35-story building. It will reach Earth on April 11 at 9:05 pm IST, flying at a speed of 64,827 km/hr.&nbsp;
However, NASA says that it does not pose any threat to the planet and will fly by at a safe distance of 1 million kilometres.&nbsp;
Asteroids from the Apollo group are near-Earth objects that cross our planet's orbit. Scientists have discovered a total of 21,083 Apollo asteroids to date, making the class the largest group of near-Earth objects.&nbsp;

The Apollo group of asteroids are named after a space rock, 1862 Apollo, that was discovered by German astronomer Karl Reinmuth in the 1930s. This was the first known object belonging to this group, and so the entire group was named after it. After being first seen in 1932, it was lost for over 40 years and was not seen again until 1973.

Astronomers will keep a watch on any asteroids that might cause any type of destruction. This is part of NASA's Center for Near Earth Object Studies (CNEOS), which looks at all near-Earth objects and measures their orbits.

NASA warns of asteroid hurtling towards Earth at scary speed

Earth is in danger of being hit by an asteroid moonlet debris that NASA blew up two years back. The DART mission, or the Double Asteroids Redirect Test, struck Dimorphos, the small moonlet orbiting the larger asteroid Didymos. The experiment aimed to understand a proposed strategy whereby potentially hazardous asteroids (PHAs) could be deflected.

The impact sent several pieces of debris flying in space and scientists say that Mars is likely to be hit by them in the future. However, turns out, that not just Mars, but our home planet also faces the dangerous prospect of being impacted. The kinetic method creates a lot of debris that can have a dangerous impact on several celestial bodies.&nbsp;&nbsp; &nbsp;

A recent study tried to understand how an impact mission like DART can trigger the formation of debris which could someday reach Earth and Mars as meteors. The results of simulations carried out as part of the study state that the asteroid ejecta could reach Mars and the Earth-Moon system within a decade. Three million particles created by the DART mission's impact with Dimorphos were tracked to learn more about what would happen to them.

The paper is available online on the arXiv preprint server and accepted for publication by The Planetary Science Journal.&nbsp;

To conduct the study, scientists used data obtained by the Light Italian CubeSat for Imaging of Asteroids (LICIACube). The CubeSat had accompanied the DART mission at the time and witnessed the kinetic impact test.

Supercomputers at NASA's Navigation and Ancillary Information Facility (NAIF) were used to simulate what would happen to them.&nbsp;

They found that some of this debris will reach Earth within 10 years, depending on their speed. So particles travelling at velocities below 500 m/s might take 13 years to reach Mars. But ejecta moving beyond 1.5 km/s (5,400 km/h; 3,355 mph) could reach Earth in seven years.&nbsp;

<h2>Is Earth at risk of asteroid debris collision?</h2>

Dr Eloy Peña-Asensio, who led the study and is a Research Fellow with the Deep-space Astrodynamics Research and Technology (DART) group at the Polytechnic Institute of Milan, told Universe Today, "These faster particles are expected to be too small to produce visible meteors, based on early observations."

She added that "meteor observation campaigns will be critical in determining whether DART has created a new (and human-created) meteor shower: the Dimorphids."

"If these ejected Dimorphos fragments reach Earth, they will not pose any risk. Their small size and high speed will cause them to disintegrate in the atmosphere, creating a beautiful luminous streak in the sky," she added.

Future Mars observation missions might also be able to observe Martian meteors, she added.

Earth in danger of being hit by asteroid Dimorphos debris. Impact might happen in...

NASA has issued an asteroid warning for August 14. Named 2024 PH2, it will zoom past Earth at a speed of 26,000 km/hr. Right now the asteroid is in the constellation of Capricorns, about 2,400,000 kilometres away from us. At its closest point, it will be 1.1 million miles from Earth. The space rock is 100 feet in size, about the size of an airplane.&nbsp;

<h2>Does the asteroid pose a threat to us?</h2>

As per NASA's guidelines for identifying a space rock as being hazardous, 2024 PH2 doesn't pose a threat. Asteroids that don't come closer than 4,650,000 million miles to Earth or are smaller than about 140 metres, that is around 460 feet, don't pose a threat. It is a Near-Earth Object (NEO) and its orbit will bring it extremely close to Earth. Based on NASA's guidelines, this asteroid becomes a potential threat. However, since it is smaller in size, it does not threaten our safety. However, a regional impact might lead to some type of destruction.

The asteroid belongs to the Apollo group of asteroids. Scientists use these events as opportunities to study space rocks. Apollo group of asteroids are categorised as near-Earth objects (NEOs) with orbits that cross Earth's path. NASA's Jet Propulsion Laboratory issues asteroid warning as part of its Asteroid Watch programme.

Asteroid 2024 PH2 will not come this close to Earth for the next 10 years. It will be visible only through long-exposure photography because it is dimly lit.&nbsp;

<h2>NASA DART mission&nbsp;</h2>

NASA's Planetary Defense Coordination Office regularly monitors asteroids moving near our planet and those that might come too close. The space agency studies these space bodies to learn more about the universe. This also helps them understand if an asteroid is on a collision course with Earth. In such a scenario, NASA will work to avert any destruction. An experiment under the DART mission aimed to understand how humans can hit an asteroid if it poses a threat to us. An impact with asteroid Moonlet Dimorphos deflected it from its path while breaking it up into several pieces.&nbsp;

NASA warns 100-foot asteroid is racing towards Earth, will be closest on...

A 104-metre-wide asteroid, which will be within 3.48 million miles of Earth, is going to pass near the planet. The asteroid has been labelled as a “potentially hazardous object”. The rock, which seems to be bigger than the iconic Big Ben, has been named Asteroid 2013 YD48 by NASA.
