The meteorite that impacted Earth and was suspected of polishing off the Dinosaurs.
It threw a lot of matter into the atmosphere and wiki article states some of it would have reached Mars and Mercury.
Why did the large amount of debris that was flung out, not form a Saturn like ring around the earth.
Because “Saturn-like rings” aren’t caused by asteroid strikes on planets, they are caused by moons breaking up.
You can have rings formed by something whacking into the Earth at high velocity. If you want something that you can actually see on a planetary scale, like Saturn’s rings, you need something roughly the size of the moon to slam into the Earth. A tiny little chunk of rock like what hit Chicxulub was pretty devastating to life on Earth, but from a ring point of view it didn’t throw up anywhere near enough stuff to make a substantial ring.
Saturn’s rings have a lot of ice in them. If the Earth tried to have icy rings like Saturn, the Sun would sublimate the ice and the rings would disappear. Mercury, Venus, and Mars would have the same problem. The asteroid belt is the dividing line. Everything inside the asteroid belt is too close to the sun to have icy rings. All of the planets outside of the asteroid belt have rings, though none are anywhere near as impressive as Saturn’s. The rings around Jupiter and Uranus are so faint that we didn’t even know that they existed until the 1970s, and Neptune’s rings weren’t discovered until the 1980s. But at least they have rings, which is more than any of the inner planets can say.
Chicxulub impact on Earth. Why no Saturn like rings around earth?
The impact was too small to eject very much material into low Earth orbit. It was an inconvenient bump in Earth history, and not a very big one. The impact had environmental consequences and that is why it seems important to us.
There’s also the fact that ring systems appear to be temporary - if long in scale - events.
Saturn’s rings appear to be lasting between 100 and 300 million years and likely represent the debris from more than one moon that collided, possibly several.
Even if the Chicxulub impact did throw up enough debris to form a ring around Earth - something I’m not willing to posit - over 66 million years it would have abraded away and we’d see no evidence available now.
It depends on what you mean by “very much”. The impact ejected material that totalled about 25 trillion metric tons, and some of it likely made it to Mars, Titan, Europa, and Callisto. I mentioned that previously. It may even have propagated life to places like Europa.
Yeah, a big enough impact would likely throw up rings – even if they later coalesced into a moon.
