The Planets - Venus.
Venus is the second closest planet to the Sun.
The information below is included to let you
know
a little more about the planets in our solar
system.
You will not be expected to
remember this information for the exam.
Venus
spins on its axis very
slowly compared to the Earth,
making one complete turn in about 243
days.
Since its orbit time is only 226 days,
Venus turns less than once
during one orbit.
Unlike Mercury, the
surface temperature of Venus
is fairly constant.
Venus is the hottest planet at
about 460°C.
The very high and constant temperature
is due to an atmosphere
of carbon dioxide, which produces a large
greenhouse effect
(see the GCSE
Chemistry site).
Venus
is the brightest of the planets.
It can be seen shortly before Sunrise and shortly after Sunset.
Of all the objects in the sky, only the Sun and
the Moon are brighter.
Venus
has no moons.
(see Summary
for further information).
