Would the consellations layout in the night sky 7,000,000 years ago be
any differnt to how we see them today?



Just ran Cartes du Ciel (Sky Charts) for 20,000 years back (max for Ciel)
and many constellations look distorted. Stars like Sirius, Procyon and
Fomalhaut have moved several degrees. Arcturus is 13° north of its current
position and Alpha Centauri is 22° away in Pavo! Ceil is good for this as
it leaves the constellation figure lines as current so you can see which
stars have drifted and by how much. That's only in 20,000 years. In 7
million years I'd expect the sky to be unrecognizable.
