The ground-based European Southern Observatory (ESO) was used to clock the asteroid duo, dubbed 1999 KW4: the pair came as close as 5.2 million kilometres (3.2 million miles) to our planet on May 25. DART stands for Double Asteroid Redirection Test, and is an experimental spacecraft that is being designed to crash into the smaller rock, or moonlet, of Didymos at 6.6 kilometres per second (4.1 MPS). Once DART is launched into space, it’ll collect enough solar energy with its solar panels to kickstart its electric propulsion system. The hope is that this impact will be sufficient enough to reroute the asteroid. The rocks were spotted and tracked by the International Asteroid Warning Network (IAWN), a group of organisations dedicated to detecting and following near-Earth objects (NEO). 1999 KW4 proved harmless to us here on Earth, though monitoring it is good practice for another NEO that may not be so friendly: Didymos.

Boffins estimate the collision will alter the moonlet’s orbital speed by one per cent, enough to allow the change to be observed and measured by telescopes on Earth. The pictures will allow the astronomers to check whether both the space rocks are composed of the same materials and how they interact with each other. Collaboration tools, such as Microsoft 365 …. The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. They allow us to count visits and traffic sources so that we can measure and improve the performance of our sites. Didymos orbits the Sun about once every two years, and the closest we've seen it come to Earth was 7.18 million kilometres (4.5 million miles) away in November 2003.

Didymos has been given the status of “potentially hazardous asteroid” as it may come even closer to Earth – some 5.9 million kilometres – in 2123, and is of large enough size to cause significant damage if it smashes into us. Dimorphos will not hit Earth The primary asteroid, Didymos, or its binary companion and target, Dimorphos, don’t pose any threat of actually hitting Earth. Asteroid 1999 KW4 flew by, did not hit Earth killing us all. Made up of two space rocks, between 160 meters and 780 meters in length, Didymos will pass Earth at a distance between 2022 and 2024. 1999 KW4 and Didymos are surprisingly similar to one another. With the idea given the green light for design, experts at the US space agency are now gearing up to prepare the craft for a outer space test in 2022. It’ll hopefully hitch a ride aboard a SpaceX Falcon 9 rocket, and will reach Didymos by September 2022. “This data, combined with all those that are obtained on other telescopes through the IAWN campaign, will be essential for evaluating effective deflection strategies in the event that an asteroid was found to be on a collision course with Earth,” said Olivier Hainaut, an ESO astronomer, on Monday this week.

A pair of asteroids just whizzed past Earth at 70,000 KPH (43,496 MPH), and although the flyby presented no danger to our home world, we can learn from the close encounter to potentially thwart any future menaces from the cosmos.
