Summary

NASA has lowered the estimated risk of asteroid 2024 YR4 striking Earth in December 2032 to 1.5%, down from 3.1% a day earlier. The European Space Agency’s (ESA) estimate stands at 1.38%.

The asteroid, 40-90 meters wide, could cause significant city-level destruction but not a global catastrophe.

The projected impact corridor spans the Pacific, South America, Africa, and South Asia.

NASA also estimates a 0.8% chance of the asteroid hitting the Moon.

    The global astronomical community expects the odds of an asteroid to hit Earth in December 2032 to eventually fall to zero.

    I love how they make it seem like some insider expertise versus knowing basics of how percentages work.

      I mean, without knowing what the number represents, it’s not obvious why it goes up and then suddenly drops like this.

      They basically predict a cross-section of places it could go through, which shrinks with improved data. If the Earth is still inside, that makes it’s share go up. Eventually, it hits an edge and the share drops to zero suddenly

    Everyone hoping there’s still a chance, you need to remember… this is only a city-killer asteroid.

    We need to hope for a much bigger asteroid.

      It’s probably made up of dense materials like iron. Let’s pile all the earth’s magnets at the White House!

        I’ll give mine, as long as someone helps with the shipping!

      Africa actually does seem to be the most likely impact if it were to hit. The predicted impact would be along the equator.

        I am down to have monthly updates for the next few years, weekly updates through 2031, and daily updates throughout 2032

        I just feel like if we do daily updates for the next 7 years when it’s in all likelihood going to miss us, we’ll be too complacent when an asteroid does have an impact trajectory

    Reminder that the asteroid is only large enough to destroy a city and, even given the rare chance of it hitting Earth, in all likelihood would land in the ocean and cause no damage. It’s not a doomsday asteroid

        Unfortunately, Washington is outside of the possible impact zone. (Well, Washington in Brazil is inside, but it’s not about that one.)

    Just give us the confidence interval and stop updating. We will know better in January 2029 once it has passed by and been tugged by our gravity and the moons.

      Why wait? The best time would have been the dawn of civilization. The second best time is now.
