I was sitting in a Volvo sedan at night with some friends in the middle of high school, in the middle of a farm field in the middle of a farming valley, in the middle of Arizona when everything turned green for about 40 seconds. It got really bright green in the middle of that time period. It took me a while, maybe 5 minutes, to postulate that the phenomenon we had witnessed was a nickel cored meteor that had overflown us along the length of the valley, some 25 miles, before disappearing over a mountain ridge perpendicular to the valley to our west, which is the direction the Volvo was facing. It was either that or the weed we were smoking had been tampered with. The meteor was mentioned in the news the next day.

In August 12, 1979, about 4 am, I was facing kind of northeast watching the Perseids meteor shower. I was in southeast Houston talking to my childhood backyard neighbor across the fence. A fireball appeared in the sky. It was about dime size wide, an arm’s length away. Maybe it’s path was a foot long, arms’ length away. It was orange yellow and maybe made a very faint, elongated, swishing sound. It travelled from about the southeast to about the northwest. Come to think of it, I may have made a similar comment a couple of years ago.

[@aromaticsnail]

We need a site/app that sends automatic alerts when and where the asteroids will be seen

[@sevenstars004]

We also need to be able to increase our chances of detecting smaller asteroids much earlier than we do now. It's likely that big ones will be detected early, but few of the smaller ones, the kind that can inflict localized damage, are detected until they are too close to be able to accurately calculate impact location, or aren't detected in advance at all. This would allow for apps that , that track satellites, ISS, etc., passing over your location, to add asteroids. People would be able to see it, or get out of the way, if it looks like it's going to impact their neighborhood.

I mean, how else could they grab them?? And it's not like the rovers have been taking samples at random, every single spot has been well considered. Regardless of Mars, I think the really interesting stuff is at the icy/watery moons of Jupiter and Saturn. We know that the Earth has life surviving kilometers in the crust, but we can't get there on Mars. BUT we can sample the emissions of the icy moons of Jupiter and Saturn! A submarine or something like that is a complete pipedream, but examining the emissions of ice volcanoes is way better than hoping to get a glimpse of life that has taken refuge kilometers deep in the Martian crust for hundreds of millions or billions of years.

[@Confuseddave]

There's another point that I'm curious about with the "20 times as big" comment. The numbers you cite are *diameters* and it's my immediate thought was that a more intuitive metric for comparing of the "bigness" of an asteroid would be it's *mass* - which, assuming it's proportional to volume goes up with the cube of diameter, would be _eight thousand_ times larger than the chicxulub impactor. Or is there some other reason to think that the "badness" of an impact scales more linearly with diameter? (e.g. the mass of a rubble pile might not strictly increase with volume, or cross sectional area might be more pertinent to the destructive potential of an asteroid?)

[@tonywells6990]

Mass and impact energy definitely scales with mass therefore diameter cubed so roughly 8000 times the Chixalub impact energy. Not sure about the impact velocity but the Jupiter system is in a deep gravity well so probably similar to Earth impact speeds. Looks like up to 20km/s so similar speed to Chixalub asteroid. Impactor energy is proportional to speed squared.

The more massive it gets the more slowly it evaporates. So it's the opposite of what you're thinking. The supermassive black holes will take 10^100 years to evaporate, but only after absolutely no more energy or matter is left to fall into them.

[@CyberiusT]

@@frasercain Thanks for the rapid reply! Actually, that's exactly what I meant - they 'eat' more slowly if they're smaller, but evapourate faster; or eat fast and radiate slowly if they're big.
