Dinosaur-killing asteroid was a rare rock from beyond Jupiter, new study reveals

[Grim Reaper 6]

The space rock that wiped out the dinosaurs 66 million years ago was a rare strike from an asteroid beyond Jupiter, a new study details. The finding pins down the nature of the fateful space rock and its origin within our solar system, and may benefit technology that forecasts asteroid strikes on our planet.

Most scientists agree that the Chicxulub impactor — named after the community in modern-day Mexico near the 90-mile-wide (145 kilometers) crater carved by the rock — came from within our solar system. But its precise origins remain unclear, due to a lack of clear chemical evidence that wasn't contaminated by Earth's own material. Now, in remnants of the impactor collected from European regions of our planet's crust, scientists have found the chemical composition of a rare element called ruthenium to be similar to that within asteroids hovering between the orbits of Mars and Jupiter..

It seems to me that them astronomers do not know where Jupiter has its orbit ...

It seems to me that:

1. you can't distinguish between the words of a journalist and the work of astronomers
2. you haven't learnt that cherry picking is a logical fallacy
3. you didn't read the entire article before making your inane comment
4. you don't understand that the solar system is a dynamic place. It is perfectly possible for an asteroid to be formed beyond Jupiter and still end up a main belt asteroid.
