What is Venus?
Venus is the second planet from the
sun.

Venus’ atmosphere is made of almost all Carbon. All of this Carbon creates a
greenhouse effect that traps all heat that enters it. This makes surface
temperatures the highest in the solar system.
C
96%
The average
temperature
on Venus is
464* C
Venus also has a
crushing
atmospheric
pressure 90 times
that of earth.
What is Venus like?

Venus has very similar diameter, density, and surface gravity to earth. The
only reason we can’t go there is because it is so hot.

Venus rotates very slowly, so it’s day lasts 243 earth days. It orbits around the
sun in 225 days. It also rotates backwards- the sun rises in the west.
Venus is also very bright
because of sulfur dioxide
droplets that make a reflective
cloud layer. This allows Venus
to be visible from earth.
What is Venus’ composition?

Venus’ surface is made of basalt and granite rocks. It appears as a rusty red or
golden brown from space.

Venus also has a lot of volcanoes, mountains, and lava plains that make its
surface a very unpleasant place to be.
Venus has a very similar interior to earth, as seen left. It has
a partly molten metal core, rocky mantle, and crust.
What about Venus’ moons or magnetic
field?


Interestingly, Venus has no moon and no magnetic field. There is not much to
Venus besides itself.
When you look in Venus’ direction, this is all you
see.
Missions to Venus

In the 1970s, the Soviet Union sent six probes to explore Venus. They
produced the idea that Venus has basalt and granite rocky landscapes.

The US sent a satellite, Magellan, to orbit Venus for 4 years to gather images
and atmospheric measurements.

It also allowed us to discover that Venus has a volcanic surface, including the
highest volcano at 8 km, Maat Mons. Scientists also think that Venus
undergoes a periodic resurfacing that covers the planet in lava.
Vocabulary

Greenhouse effect: the warming of the surface and lower atmosphere of a
planet that occurs when 𝐶𝑂2 and other gases in the air absorb and reradiate
infrared radiation

Atmospheric Pressure: the force per unit area that is exerted on a surface by
the weight of the atmosphere

Rotation: the spin of a body on its axis

Revolution: the motion of a body that travels around another body in space;
one complete trip along an orbit
Facts on Venus
Venus
Size: 12,104 km, or 95% of earth’s diameter
Color and surface features: Surface has a lot of lava and volcanoes, color is
red/orange
Length of day: 243 days per rotation, Length of year: 225 days per revolution
Density: 5.2 g/cm^3 or 95% of earth’s density
Gravity:91% of earth’s gravity
Atmosphere: Carbon dioxide 96%, Nitrogen 3.5%, 0.5% Trace elements
Surface Composition: The surface of Venus is made of basalt and granite rocks,
along with lava on a smooth surface. There are a ton of volcanoes.
Interior composition: It is predicted that Venus has a rocky mantle and liquid
core, although it is not known for sure what is inside of Venus.
Magnetic Field: Venus has no magnetic field
Moons: Venus has 0 moons
Unique things about Venus: Venus is the hottest planet in the solar system, it
rotates backwards, and it is brighter than all stars in the sky besides our sun.
