Venus-The
Sun rises from the west.
We
often use "Unless the Sun rises in the west…" to imply the impossibility
because on the Earth, the Sun rises in the east. But please remember
never use this phrase on Venus; on Venus, the Sun rises in the
west and sets in the east. This phenomenon was caused by the different
rotation direction of the Earth and Venus. Venus rotates from
the east to the west and the Earth rotates in other direction.
Venus's
diameter is 0.95 times of the Earth and two planets have the similar
density and size. For centuries, Venus has been regarded as sister
planet of the Earth. After more in-depth exploration and analysis,
Venus was found as a total different surface environment.
There
is Atmosphere on Venus's surface but 90% is composed by carbon
dioxide. There is no ocean to disperse carbon dioxide on Venus
and that causes the accumulation of carbon dioxide and strong
Greenhouse Effect. Surface temperature of Venus reaches to 450°C
so it is very hot. In addition, air pressure of Venus is 900 times
of the Earth.
Venus
is covered by heavy clouds consisting of sulfuric acid. 60% region
of Venus is flat and it also has mountains, basins, and canyons
similar with the Earth.
Rotating
speed of Venus is quite slow. In equator, the rotating speed is
only 1.8 kilometer/second and the Earth has the speed of 465 kilometer/second.
Thus,
the intensity of magnetic field is only 1/100,000 of the Earth.
It takes 243 earth days for Venus to rotate and its revolving
period is 224.7 earth days. One day on Venus means two year on
Earth and each year on Venus has two days.
Earth
is only planet known to have living creatures. Among planets,
it is the heaven of human beings. But human destroy the environment
constantly and has no solution to greenhouse effect. The high
temperature on Venus caused by greenhouse effect teaches us a
lesson. We should do our best to protect our living environment.
