Venus
is called the Evening Star. It is called this because it looks so bright to us
from Earth. Venus and Earth are almost the same size. Venus is the closest
planet to Earth, but it does not have oceans or human life like Earth. Venus
gets so hot during the day that it could melt a lead cannonball. The temperature
rises to 484 degrees
Celsius on the side facing the Sun. Venus has very
thick, rapidly spinning clouds which cover its surface. These clouds hold heat
in. That is why Venus gets so hot. These clouds also
reflect sunlight. That is why Venus appears so bright
to us here on Earth. There are constant thunderstorms in these clouds. The
surface of Venus has many
craters which were made by
meteorites and
asteroids crashing into the planet. Venus also has
volcanoes. This planet is unusual because it
rotates in a direction opposite that of all of the
other planets. Venus spins very slowly as it
orbits the Sun
of love.
Facts about Venus:
- (1) Venus
is about the same size as Earth.
- (2) Venus
rotates in a retrograde (backward) direction.
- (3) At its
closest, Venus is only 42 million kilometres (26million miles) from Earth.
- (4) Venus
has a thick atmosphere of carbon dioxide. Atmospheric pressure at the surface
is 90 times that of Earth.
- (5)
Because Venus is nearer the Sun than Earth and has a very thick atmosphere,
the surface temperature is extremely high, as much as 475° Celsius (900 °
Fahrenheit).
