Possible Interstellar Object That Buzzed Earth Earlier This Month
- aaron695 9y agoThis seems to me like it is simply not possible? Has anyone done the statistics to see if it is possible (I assumed this has been done years ago)? I would have thought it would not even be considered a possibility. Or does it have some sort of link to our solar system and left and now has returned? What do they exactly mean by interstellar.
- pohl 9y agoRegarding the question in your last paragraph: I believe it comes down to the velocity being so great relative to the solar system’s gravity well. See the “hyperbolic orbit” phrase in this entry: https://en.wikipedia.org/wiki/A/2017_U1 https://en.wikipedia.org/wiki/A/2017_U1
