Huge 'planet-killing' asteroid detected, and it's headed in our direction.
According to astronomers, they have spotted the largest planet-killing asteroid in the past eight years, and the massive space rock will cross Earth's orbit. The 2022 AP7 asteroid was discovered by researchers searching for space pebbles between the orbits of Earth and Venus. Scott Sheppard and colleagues at the Carnegie Institution for Science in Washington report in the Astronomical Journal that they have discovered three "quite huge" asteroids, one of which - 2022 AP7 – crosses Earth's orbit, making it a potentially hazardous asteroid (PHA). With a diameter between 1.1 km and 2.3 km, 2022 AP7 is the largest PHA detected since 2014 and likely within the top 5% largest ever discovered. "Any asteroid larger than 1 kilometre in diameter is regarded a planet-killer," said Sheppard, adding that if such an object were to strike the Earth, the impact would be catastrophic for life as we know it, with dust and toxins sent into the atmosphere, where they would rem...
