   Is Apophis a safe asteroid?

   • Earthlings can breathe a sigh of relief after US space agency Nasa confirmed the planet was "safe" from a once-feared asteroid for the next 100 years at least. Nasa had deemed Apophis to be one of the most dangerous asteroids to Earth after its discovery in 2004. Close calls in 2029 and 2036 were predicted and later ruled out.

   How dangerous is asteroid 99942 Apophis?

   • After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.

   Is Apophis a threat to Earth?

   • Apophis was discovered in 2004, and immediately assessed as a potential threat. Early projections suggested it had a very worrying 2.7 percent chance of slamming into Earth on its 2029 flyby. That was ruled out pretty quickly, but Apophis' orbit brings it to an Earth flyby every eight years.

   What would happen if Apophis hit a highly populated area?

   • Even though it won't come close to the devastation caused 65,000,000 years ago by the asteroid that wiped out the dinosaurs and two-thirds of all species on Earth, millions of people would die if Apophis hit a highly populated metropolitan area.

   What if Apophis hit Earth?

   • These low odds are fortunate considering the huge damage Apophis would cause were it to strike Earth. The Planetary Society estimated that if Apophis were to hit Earth it could release energy equal to more than 1,000 megatons of TNT, equivalent to the detonation of tens or even hundreds of nuclear weapons.

   Will asteroid Apophis impact Earth in 2068?

   • New observations of asteroid Apophis – thought to pose a slight risk of impacting Earth in 2068 – rule out any chance of impact for at least a century. After 17 years of observations and orbit analysis, ESA is removing the enormous asteroid from its Risk List.

   Mar 6, 2024 · Based on the current data, there's no risk of collision. Apophis may pass another asteroid called Xanthus in December of 2026 within 10,000 kilometers (6,200 miles); they won't hit, but it is possible that any unseen debris tagging along with Xanthus, if it exists, could hit Apophis.
