2029 - Torino scale 4

Although 2004MN4 now seems to be a false alarm it may still prove an
interesting object. Present estimates indicate mean and perihelion distances
between Venus and Earth and an aphelion distance between Earth and Mars. The
only confirmed body with these characteristics is Aten.

Damnit! There's a few dinosaurs I'd like to have seen the end of.

Sometimes people post immensely long URLs and they don't wrap in my
newsreader (Agent) and sometimes long ones do - as did yours and
Stephen's. URL... made not difference. It's this random contrariness
that keeps the net from conquering us by ensuring that we have blood
pressure raising blistering rages every now and then.

Closest approach is currently estimated at 0.0003431 AU. It could be as
little as 8 Earth radii. The following page has a nice summary:

Astronmers - they just can't cope with small numbers, can they?
Finally given a measurement that would be easily (and best) expressed
in miles or kms, they go for 100 thousandths of an AU.

Looks more scary that way though, doesn't it? DOOMED, WE'RE ALL DOOMED!

I certainly did a double-take when I saw all those zeroes.

It was for that sort of reason that I included "with good software".
Six-year-old software can understand the form; I don't know how much
longer it's been in use.

But one must discriminate between wrapping at the composing stage,
wrapping at the sending stage, and wrapping at the displaying stage. If
the material was in a wrapped state during transit, then it should be
displayed with that wrap; if it was not, then it should be possible to
display it without added wrap.

I composed that wrapped, IIRC; it was certainly transmitted wrapped, the
intention being that it would be displayed wrapped but recognised, with
good software, as a logical unit.

Most people (here being atypical) post with MSOE and let it do whatever
it wants, when they could (I hope) easily extend the line when posting
73-character URLs.

They could have gone for 0.00000000166 parsecs
