Remember the Telsa Roadster that Elon Musk launched into space last week?

Well, three scientists just took a close look at the vehicle's orbit over the next million years, and they found there is a slight chance the car might crash into Earth or Venus.

Don't panic. The chance is pretty small - somewhere around 6 per cent for Earth and 2.5 per cent for Venus. And a million years is a very long time - our species has only been around for about a fifth of that span.

There's plenty of room for civilisation-ending catastrophes to occur long before the Tesla re-enters Earth's atmosphere.
