Venus
Venus is the second planet from the Sun. It is named after the
Roman goddess of love and beauty. As the brightest natural object
in Earth's night sky after the Moon, Venus can cast shadows and
can be, on rare occasions, visible to the naked eye in broad
daylight.
The similarity in size and density between Venus and Earth
suggests they share a similar internal structure: a core, mantle,
and crust. Like that of Earth, the Venusian core is most likely at
least partially liquid because the two planets have been cooling
at about the same rate.
Much of the Venusian surface appears to have been shaped by
volcanic activity. Venus has several times as many volcanoes as
Earth, with 167 large volcanoes that are over 100km (60mi) across.
The only volcanic complex of this size on Earth is the Big Island
of Hawaii.
