    There's a mad dash amongst the astronomical community to observe the recently discovered comet Borisov (I shit you not, that's its name !! :eek:) What's got astronomers in bother is that the orbital details of this thing suggests it has interstellar origins. It is coming in at a high angle to the orbital plane of the solar system, and moving at about 30 kilometres per second. Too fast to be a solar captive. It has now been classified as a comet because it's outgassing a tail. It will be closest to the Sun just beyond the orbit of Mars in late October and then sail off into the great black yonder never to be seen again.
    A literal flash in the pan.

    It's official. Comet Borisov is an interstellar visitor rather than a local. (And by local I mean anything up to a light year or so !!) It will be around for a few months, will never get anywhere near the Earth and unless something dramatic happens, not be naked eye visible. It is the first interstellar comet ever observed and is thought to be between 2 and 10 miles in size. Given the speed it's travelling at that would make it a true planet killer but the closest it will get is far outside the orbit of Mars.

    It's journey past the Sun will alter it's trajectory as it heads out into deep … and I mean deep … space, never to return.

    Two interstellar objects within a couple of years means observation techniques are likely getting better and such visitors may be more common than previously thought. (Or, we are under attack but the aliens involved are just lousy shots. :heyhey: ) It was discovered by an amateur astronomer Gennady Borisov from the Crimea using his home made 25 inch telescope, which must be quite a beast !

    If it changes course I'll let you know .. as that could mean we're in deep shit. :eek:

    Would be a welcome distraction from Brexit though.

    You know it never occured to me that you invented the telescope.

    Tell me, do you mount it on a tripod or a plinth?

    Wow have you got your knickers in a twist. :buddy:

    In the immortal words of Harry Enfield: "Kalm down Kalm down."

    Think of your blood pressure. Perish the thought you'd stagger off the Plinth … (or could it be the Iron Throne.) :bum:
