back to article Astronomers testing next-gen asteroid-hunting algorithm discover potentially hazardous object

Astronomers have spotted a potentially hazardous asteroid thanks to a new algorithm that will be deployed in the upcoming Vera C Rubin Observatory in Chile, which is currently under construction. Asteroid 2022 SF289 was first spotted last year when researchers began testing the HelioLinc3D algorithm on data collected in the …

    And they need to hurry up about it since our present asteroid defense system is to be retired by Quentin Tarantino in the near future!

      Entirely possible that they'll miss something. 2023 NT1, for example, passed at 1/4 of the Moon's distance on July 13th, but wasn't spotted until July 15th. It wasn't that big - around 30 metres - but compared to, say, the Chelyabinsk meteor, which was around 18 metres, it was big enough to cause a very bad day locally if it had hit. Hopefully the new systems coming online soon will be better at spotting asteroids coming in from near the Sun's direction.

        Ugly truth: for the foreseeable future, this mission does not care about a "very bad day locally". It's about "a very bad day globally". Sure, if we can spot and have time & money to deal with a smaller problem, we'll go for it. But even the loss of a hundred thousand souls just isn't big enough for this. Yet.

    Astronomers are great scientists

    It's very comfortable that they are doing the research that could help us work to stop a big rock arriving unexpectedly. Certainly there's no guarantee about what could happen but they are working to make life better for the world (icon). I'm always a little concerned that we have not been hit by a large asteroid for thousands of year but there have been strikes in the past and just a few very small ones in my lifetime. So a strike is possible but their work suggests that it's not very risky these days.
