#OSIRISAPEx #Apophis

in 2029
by and by
Apophis flew
its gravity declined
by distance
to the negative two
far too small
to rattle me and you

Apophis is one of those close orbit asteroids that newspapers like to say is definitely going to destroy us on some future date because if it's not 'Aliens' its 'Doomsday' with Space stories.

Instead looks like we're going to land on it and follow it around!

Apophis is (officially) calculated to come closer to Earth than the GOES satellites.
