How is this possible? If space outside the solar system is empty, then the probability of 2 extrasolar comets should be 0 during my lifetime.

- rebolek 7y agoWhy should it be empty?
- slantaclaus 7y agoYeah who said it was empty?
- penagwin 7y ago> If space outside the solar system is empty, Empty? You've seen stars in the night sky before surely?
- chousuke 7y agoThe space outside the solar system is mostly empty, but also really big. Maybe these things are more common than we think. Rare events also happen all the time; something being extremely improbable doesn't mean it will never happen.
- mcbits 7y agoIt's possible because "empty" is a relative term and the solar system is big. Hell, a whole 'nother star system passed through the solar system (if we include the Oort cloud) just 1,000 lifetimes ago. https://en.wikipedia.org/wiki/Scholz%27s_Star https://en.wikipedia.org/wiki/Scholz%27s_Star
- GuiA 7y agoMan, it’s pretty crazy that it passed in the solar system, but its peak apparent magnitude was 11. Space is weird.

So it's either hourly or more, there might be thousands of various sizes each day for instance. Or these are fake news. Old bits of junk coming back. People are finding oddities in the massive amount of space debris and claiming they are something else. But yea, these are not explained properly. The story is missing the logic part. Which to me means it's probably option 2.
