Quoting: Anonymous Coward 77356218 They could always send up the Space Force and blast it with nukes. Then you'd have smaller chunks to worry about instead of a 6 mile wide asteroid... |

I am in Somerset, UK Depends on where the planets are relative to each other, there's no one time of year. Jupiter was best back in July of this year. Next year it will be best in August. For the best time to see Jupiter look up the opposition dates. |

Sit back and get wasted? Rape and murder? Post on GLP? Post to GLP, of course. While getting wasted. Not so much into the raping and murdering part, but I'd have my AR-15 strapped to me in case someone else tries either of those. the towering mountains of coastal florida will totally shelter you in place bro.....no worries |

I seems big that was all how it arrives and vanishes seemed odd. That's a cosmic ray strike. They're quite common, it's radiation from space colliding with the CCD and creating a charge across one or more pixels in a single frame. Like hot pixels they do not form point spread functions the way stars and other point-like sources of light do in the telescope. |
Anonymous Coward User ID: 46432626 United States 09/23/2020 11:30 AM Report Abusive Post Report Copyright Violation | The gist of it?: bigger than originally thought but still not going to hit. Right? Quoting: Anonymous Coward 79399667 No, As mentioned in the video it's not possible to rule out the possibility of impact. It is possible to set upper limits on the size that are way smaller than 6 miles. Those are upper limits, that's it, it doesn't mean that it's actually larger than originally thought. In reality though, a size of only a few feet wide means that it's not going to be practical to detect it prior to the potential impact. so.... if we built this large wooden Badger... |

Midwest Skeptic User ID: 77374864 United States 09/23/2020 11:55 AM Report Abusive Post Report Copyright Violation | Astromut please keep us up to date, particularly as more information comes in on it's size. Even a "miss" at the distance they are talking about with a large size rock of the upper size range they are talking about is one scarey event. This rock should serve as to a wake up call as to the real risk the planet faces wrt incoming meteors. |

Quoting: Midwest Skeptic 77374864 Even a "miss" at the distance they are talking about with a large size rock of the upper size range they are talking about is one scarey event. The upper size based on the data from two years ago is still just a matter of feet, it's nothing to be worried about. The upper limit I can set is much higher only because it's not possible for me to detect it, nor will it be possible prior to either impact or the miss. I did rule out an extinction level event though, and I see no indication that NASA is trying to hide any such event here. |
