NASA has classified this asteroid as “potentially hazardous” for its “potential to make threatening close approaches to the Earth”.

It’s now estimated that if Bennu hits the earth it would detonate with the power of 1.1 billion tons of TNT, 55,000 times more powerful than the bomb dropped over Hiroshima.Īccording to NASA the asteroid 7482 (1994 PC1), which measures more than 3,280 feet across, could come within five lunar distances of Earth on January 18. By the time we’ll know if the asteroid would hit us or not, we may have some type of defense in place – and the road to that starts with Double Asteroid Redirection Test (DART) that launches this November. NASA says we now have a better understanding of the trajectory of the asteroid thanks to OSIRIS-Rex. See “Ephemeris and hazard assessment for near-Earth asteroid (101955) Bennu based on OSIRIS-REx data” A study that sought to better understand the trajectory Bennu will take from now and until about the year 2300. The OSIRIS-Rex data was compiled in a study published earlier this August in the Icarus scientific journal.

a spacecraft tasked with taking a piece of the asteroid Bennu and bringing it back to Earth in 2023. In 2016, humanity launched into the void a spacecraft called OSIRIS-Rex. Next Century, the Asteroid Might Poke Back” These type of exercises are specifically identified as part of the National Near-Earth Object Preparedness Strategy and Action Plan developed over a three-year period and published by the White House in June 2018. The fictitious impact scenario will occur during the 7th IAA Planetary Defense Conference, hosted by the United Nations Office for Outer Space Affairs in cooperation with the European Space Agency agencies and space science institutions, along with international space agencies and partners, to use the fictitious scenario to investigate how near-Earth object (NEO) observers, space agency officials, emergency managers, decision makers, and citizens might respond and work together to an actual impact prediction and simulate the evolving information that becomes available in the event an asteroid impact threat is discovered. The exercise depicting this fictional event is being led by NASA’s Jet Propulsion Laboratory’s Center for Near Earth Object Studies (CNEOS), allowing NASA’s PDCO and other U.S. ĭuring the week of April 26, members of NASA’s Planetary Defense Coordination Office (PDCO) will participate in a “tabletop exercise” to simulate an asteroid impact scenario. In this instance, the scientists discovered a small thermal reaction which could slightly alter Apophis’s course. The Yarkovsky effect is when an asteroid or celestial body changes its orbit due to small push of heat, either from itself expelling gasses, or the gravitational push and shove from celestial bodies including the Sun and Earth. Scientists at the University of Hawaii detected a small Yarkovsky acceleration on the surface of the asteroid Apophis which could influence the asteroid’s path for its 2068 flyby. However, on April 13, 2029, Apophis will get closer to the Earth than some of the highest-orbit satellites surrounding the planet. The asteroid posed no hazard to the Earth on this flyby as it was more than 40 times as far away from Earth as the moon. On Friday, a large asteroid roughly the size of the Eiffel Tower zipped past the Earth.
