History of Venus

Venus is the Roman

Goddess of Love and

Beauty. In Greek

Mythology, she is alsoknown as Aphrodite.

This is the sign for

Venus.

BASIC FACTS OF VENUS

Venus was first discovered by a caveman who mistook it for astar. Ancient Greeks also wanted to learn more about Venus asa star

Venus is the second planet from the Sun

Venus is nearly the same size as Earth

12,102 km in diameter(12,756 km for Earth)

82% the mass of Earth

Similar density, 5.3 g/cm3 (5.5 g/cm3 for Earth)

Venus takes 223 days to orbit the Sun

Venus takes 2,243 days to rotate on it axis and it rotates theopposite direction of Earth

EARTHS SISTER

Venus is sometimes called

Earths twin orsisterbecause the planets are so

much alike. They are almost

the same size and they both

have relatively young

surfaces. They also are

similar in chemical anddensity compositions.

LAYERS OF VENUS

Crust-the Venusian crust is comparably thin, extending a depth of 30 miles. The surface is

remarkably flat, with on 10% of the planet having a relief. The thin crust is one of the

reasons why Venus was geographically active in the recent past.

Mantel-below the crust is a rocky mantel, again solid, extending almost from the surface

to a depth of about 2,000 miles

Core-large metal core, probably composed of the metal nickel and iron, which takes up

about half of its radius. The planet has a weak magnetic field, so its core could possibly

be solid.

VOLCANOES

Venus is a planet with wide-scale volcanic activity

In the lowland plains, lava renews the surface anderases craters

The are many volcanoes associated with surface hotspots

The largest volcano on Venus is Sif Mons

3 km high, 500 km across

Caldera is 40 km across

These volcanoes result from magma reaching thesurface

Pressure under the surface can cause bulges calledcoronae


9/18

TEMPERATURE OF VENUS

Venus is very hot. It can heat up to over 867

degrees F. The cause is the thick yellow

clouds (formed from a poison called Sulfuric

Acid) all around the planet. It is cal led the

greenhouse effect. The clouds trap the

heat, causing the planet to get hotter and stayhot.

Visitations to Venus

More than 20spacecraft's havevisited Venus. The veryfirst one was Mariner 2,

which visited Venus in1962. Some of the otherspacecraft's includePioneer Venus, Venera7, and Magellan.

THE MAGELLAN MISSION TO VENUS

The Magellan mission to Venus was launched May 4, 1989 and arrived at Venus onAugust 10, 1990

Magellan used a high resolution radar to map the surface of Venus through theopaque clouds

Magellan worked for 4 years and mapped 98% of the surface of Venus

MAPPING SURFACE OF VENUS

The Magellan data can be processed into 3-D views of the surface of Venus

from radar images from the Magellan

space craft

GRAVITATIONAL FORCE

If a 150 pound person went on Venus. They would weigh 132 pounds.


14/18

VENUSS ATMOSPHERE

The atmosphere of Venus causes a very high surface temperature and gives thesurface a perpetual red twilight

The weather at the surface is hot, dry, calm

The pressure at the surface is 90 times the Earths atmospheric pressure

Carbon Dioxide 96%

Nitrogen 3.2

Other .8%

VENUS: LOCATION & ORBIT

This close proximity to the Sun accounts for the average surface temperature on Venus of

482 degrees Celsius. It takes 0.62 Earth years, or 225 Earth days, to complete one

revolutionary period and 243 Earth days to complete a rotational period. This makes a

Venus day longer than a Venus year! At an orbital inclination of 3.39 degrees and an

eccentricity of 0.0068, the planet's orbit about the Sun is almost perfectly circular.

PHASES OF VENUS


17/18

TIME ON VENUS

One day on Venus would be 243

Earth days. One year on Venus

would be 224 Earth days. That

means that a day is longer than a

year on Venus.
