Explanation:
Venus is currently the brilliant evening star.
Shared around world,
in tonight's sky Venus
will begin to wander across the face of the lovely Pleiades star cluster.
This digital sky map illustrates the path of the
inner planet
as the beautiful conjunction evolves,
showing its position on the sky over the next few days.
The field of view shown is appropriate for binocular equipped
skygazers
but the star cluster and planet are easily seen with the naked-eye.
As viewed from
our fair planet, Venus
passed in front of the stars
of the Seven Sisters 8 years ago, and will again 8 years hence.
In fact, orbiting the Sun
13 Venus years are almost equal to 8 years on planet Earth.
So we can expect our
sister planet to visit nearly the same place
in our sky every 8 years.
