From the article:
One of them, 2022 AP7, is roughly a mile long, and its orbit crosses Earth’s path around the sun, getting as near as 4.4 million miles to Earth itself — uncomfortably close by cosmic standards (although far more distant than Earth’s moon). That makes 2022 AP7 “the largest potentially hazardous asteroid found in the last eight years or so,” said Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C., and an author of the study.
It will pass by the Earth 18 times further than the moon so no doom... this time.
But they claim it will be effected by the Earth’s gravity and will have a different path the next time around. Something for the grand kids to worry about.
Wonder what the effect will be if it's affected by E's gravity
Predicting orbitals is a much harder problem than most people realize, especially if you want to look several orbits in the future. Look up "three body problem" in your favorite search engine.
