Explanation:
Is that Venus or an airplane?
A common ponderable for sky enthusiasts is deciding
if that bright spot near the horizon is the planet Venus.
Usually, an airplane will show itself by
moving significantly in a few moments.
Venus will set only slowly as the Earth turns.
Still, the identification would be easier if Venus did not keep shifting its position
each night.
Pictured above,
Venus was captured on 44
different nights during 2006 and 2007 over the
Bolu mountains in
Turkey,
when Earth's sister planet appeared exclusively in the
evening sky.
The average spacing of the images was about five days, while the images were always
taken with the
Sun about seven degrees below the horizon.
That bright spot toward the west in your
evening sky this month might be neither
Venus nor an airplane, but
Mars.
