    whew...(wipes brow)....another near miss...

    yesterday , a small lump of rock around 10m in dia whizzed past us between the moon and our earth at 56,200km/h

    just imagine ...if it was just a small part of 1 degree different in it's trajectory....

    there'd be no toilet paper left on earth, because everyone would have **** themselves

    It might be 10M out there, but how big would it be by the time it hits the deck?

    I dunno, I assume 10m, do you have a theory on this?

    I doubt it'd be 10mm, most of it would burn up, due to friction, upon entering the atmosphere.
    If you don't like trucks, stop buying stuff.

    2ND ONE IN A WEEK.......

    Yes, another one just whizzed by , closer to Earth than to the Moon.

    A "potentially hazardous asteroid" known as 2020FL2 , 21mtrs in dia , just blasted past Monday at 73,000kmh.

    If it hit it would be seriously 'night Al , night Tec' , for us all.

    They never tell us in advance that an asteroid could possibly collide......that would create more panic buying than covid19 , you would really need the toilet paper.

    Missed that one, although I pro'ly wouldn't see it if it didn't have some burn time in the earth's atmosphere. I do often see the satellites go over my house, some of them even seem to flare, not sure why.

    A lot of satellites have highly reflective surfaces on them for temperature stabilisation, and these can reflect sunlight very brightly, but only when it is at the right angle relative to you, the satellite and the sun. Visualise the flash you can get from a flat windscreen when driving and the setting or rising sun is just at the right angle. Most times it will be as the angle changes with the position of the satellite, but some may be because the satellite is tumbling.

    It's called Iridium flare.

    If you goto Heavens Above www.heavensabove.com you can look up Iridium flares and see them in daylight.

    I think you mean Heavens-Above with a dash, the way you have it may be an adults only site as my computer complained!
