    Alan Duffy was confused. On Thursday, the astronomer's phone was suddenly flooded with calls from reporters wanting to know about a large asteroid that had just whizzed past Earth, and he couldn't figure out "why everyone was so alarmed."

    "I thought everyone was getting worried about something we knew was coming," Duffy, who is also lead scientist at the Royal Institution of Australia, told The Washington Post. Forecasts had already predicted that a couple asteroids would be passing relatively close to Earth this week.

    Then he looked up the details of the hunk of space rock named Asteroid 2019 OK.

    "I was stunned," he said. "This was a true shock."

    How many more of these "little"
    surprises are out there and when will
    one hit???
    May the FORCE be with you!

    Lots and probably sooner rather than later.
    Cast your burden on the Lord,
    and he will sustain you;
    he will never permit
    the righteous to be moved.
    Psalm 55:22

    From the NYT story:

    NASA and other space agencies keep close tabs on Near-Earth Objects, those space rocks whose paths come even remotely close to our planet’s orbit. NASA considers it their main avenue of planetary defense, and has been charged by Congress to find at least 90 percent of NEOs 460 feet (140 m) across and larger. Asteroids smaller than that probably wouldn’t cause a planet-scale catastrophe, though they could be quite damaging, depending on where they hit.

    For reference, the asteroid purported to have killed the dinosaurs 66 million years ago was about 10 miles (16 km) across, if not larger, while the meteor that flew over Chelyabinsk, Russia in 2013 was only 66 feet (20 m) across.

    So if 2019 OK had struck Earth, it could have delivered quite the blow to any city it struck, but would not have been a world-wide event. Experts suggested it would hit with some 30 times the power of the atomic bomb that destroyed Hiroshima.

    But the real effects are unclear, because there’s still uncertainty about how big the asteroid was. The large range, between 187 and 426 feet (57 to 130 m), occurs because astronomers can really only measure how bright the object is. A shinier object could be on the smaller end of the range, while a darker, less shiny target might be on the larger end.
    It's not how old you are, it's how you got here.
    It's been a long road and not all of it was paved.
