Venus - The Evening "Star"
To the surprise of
many, the planet Venus appears to us to go through phases just
like the moon. It transitions from full and new phase visually
nearest the sun to a crescent, quarter, and gibbous phases
further from the sun. This is because Venus is closer to us than
the sun, therefore we see its dark side regularly (unlike Mars,
Jupiter and the other planets that are further than us from the
sun. Venus is named for the Roman goddess of love, perhaps
because it is so beautiful at its brightest in the evening and
morning skies. After the sun and the moon, Venus is the
brightest object in the sky, reaching over 25,000 times brighter
than the faintest stars you can see at night. In the darkest
locations on planet Earth, Venus can actually be seen to cast
shadows. While perhaps one of the most beautiful naked eye
planets, Venus is by no means a lovely place to visit. Its
atmospheric pressure is about 100 times that of earth with a
temperature approaching 900° F. Venus has a very thick
atmosphere with clouds that are highly reflective giving it such
a bright appearance. Sometimes clouds can be seen in earth based
images, but this image is pretty devoid of such features.
