WHERE IS THE PLEIADES?

The actual Pleiades.


RATIONALWIKI.COM

The actual Pleiades is an open star cluster, about 400 light-years from Earth. It consists of 7 stars that are visible to the naked eye and a bunch that are too dim to see without a telescope.
The cluster is very young, no more than 150 million years old. Any planets orbiting the stars of this cluster would also be equally young. In fact, when the Earth was 150 million years old, it was still in the Hadean eon, characterized by regular impacts from asteroids and comets. Its surface was largely molten due to the constant, relentless impacts. It would be another two billion years before oxygen first appeared in its atmosphere.
In other words, if space aliens did evolve on any of the (hypothetical) worlds in the Pleiades cluster, they'd be bacteria.
