Who knows, if an asteroid is discovered which WILL strike the earth,
they might tell you before it actually becomes visible in the day sky...

More likely, though, they will inform the public when the rumors and
back channel information is no longer deniable


As for this asteroid "ALH2804-C"...? ?

The designation "ALH" is used to designate recovered meteorites from
Antarctica, some of which seem to have originated on Mars. Thus, this
designation for an incoming body is bogus.
