2024 YR4 and other dangerous asteroids
- hermitcrab 2y agoAn interesting overview of the danger of asteroids.
- p2detar 2y ago> 5 lunar distances (LD) I think this is the first time I see this distance notation. You learn something every day I guess. Now I wonder if an Asteroid passing < 1LD is basically always a hit.
- hermitcrab 2y ago>I wonder if an Asteroid passing < 1LD is basically always a hit. The distance earth to moon is approx 4 x 10^8 m. If an asteroid is 10^2m across, there are an awful lot of orbits that will go between the two and not hit the earth.
- gus_massa 2y agoI agree. Here is an image with the Earth, Moon, and orbit distance to escale. https://tomroelandts.com/articles/earth-moon-system-to-scale https://tomroelandts.com/articles/earth-moon-system-to-scale

- martinclayton 2y agoInformation-rich but is sadly very click-baity. The head/title of the page is: "Asteroid to Hit Earth 2025 | Most Dangerous Asteroid 2025". Heading is "Next Asteroid Predicted to Hit Earth: All About 2024 YR4 and Other Dangerous Asteroids". Then big picture of bad things happening: "Are We Doomed?" Body text kicks off with: "Every now and then, the media produces dozens of scary headlines about rocks from space headed toward our planet." ...like this one, you mean? There's a section headed "Famous asteroids predicted to hit Earth". Why use this misleading style? The body text below this heading can be summarised as: "there are no famous asteroids predicted to hit Earth". At least it says "At this time, there is no evidence that any of these asteroids will collide with Earth". Sounds like "so you're saying there is a chance!"
