THE “TWIN PLANET” OF EARTH

Venus is the second planet from the Sun,
making it hotter than our planet.
It is part of the milky way galaxy, between two
“arms” of the spirals.
Not this one
The temperature on Venus is
about 860 degrees
Fahrenheit, Because it is
close to the sun.
Venus got its name from the Roman
goddess of love.
In Greek, the goddess of love is
Aphrodite.
In Babylonian, her name is Ishtar.

Venus’ orbit is elliptical and counter-clockwise.
Venus takes approximately 243 days to orbit
the Sun.
Venus' atmosphere is nearly 100 times as massive as Earth's, and its thick
cloud layers block the surface from view. It exerts a pressure of
approximately 92 bars at the surface. Its composition is nearly all CO2.
The density at the surface is 65,000 g/m3. Wind speeds range from 1-4
km/sec at the surface. The scale height of the atmosphere is about 15.9
km.

Life cannot be supported on Venus, unless it
was very tough and could withstand high
gravity, could use CO2 like we use oxygen, and
have a slow metabolism.
Sorry but Venus has
no moons.
Venus has no water on its surface, and very little
water vapor in its atmosphere. Scientists think that the
runaway greenhouse effect that makes Venus so hot
today boiled away its oceans long ago. Since Venus
lacks a planetary magnetic field, the Sun’s solar wind
was able to blast the hydrogen atoms out of Venus’
atmosphere and into space. Venus can never be cool
again.
Most of the surface of Venus is covered by smooth
volcanic plains, and its dotted with extinct volcanic
peaks and impact craters. Venus has much fewer
impact craters than other planets in the Solar System,
and scientists have estimated that some event
resurfaced Venus between 300-500 million years ago,
wiping out all of the old impact craters and volcanoes.
A LONG, LONG TIME AGO, IN A
CLASSROOM JUST DOWN THE
HALLWAY, WE STARTED THIS
POWERPOINT.
NOW IT IS OVER.
THANK YOU FOR YOUR ATTENTION, AND
WE HOPE YOU LEARNED SOMETHING
FROM US.
