VENUS

Members: JAVIER POLANC O AND GERARDO GOMEZ

The planet

VENUS , the second planet from

the sun, is often referred to as

one of the “ inner planets”.

It’s one of the first FOUR planets

closest to the sun.

The inner planets

V e n u s m e a n s :

In astronomy mythology, Venus

was the Roman goddess of love

and beauty.

In Greek, her name was

Aphrodite.

Like the Earth, Venus has an

Atmosphere.

It is far thicker than that of the

Earth, making it diffi cult for

modern science to penetrate.

The Earth Has a Sister

Venus is in many ways Earth's

sister planet. It is almost

identical in size, chemistry,

gravity and density as the Earth.

Venus has volcanoes, mountains

and sand, just l ike Earth.

Venus is Dry

 Venus does not have an ozone layer. The ultraviolet radiation from the Sun finds ITS way directly into Venus' atmosphere. Over many years a billion of this radiation has slowly broken down water molecules into Hydrogen and Oxygen. 

Venus is one of the four terrestrial planets in the Solar System, meaning that, like Earth, it is a rocky body. In size and mass, it is similar to Earth, and is often described as Earth's "sister" or "twin". The diameter of Venus is 12,092 km (only 650 km less than Earth's) and its mass is 81.5% of Earth's. Conditions on the Venusian surface differ radically from those on Earth, owing to its dense carbon dioxide atmosphere. The mass of the atmosphere of Venus is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen

Instead of the Sun rising in the east and setting in the west, the Sun on Venus would appear to rise in the west and set in the east.

 Moons: Venus has no moon. Venus may have possessed oceans in the past, but

these would have vaporized as the temperature rose due to a runaway greenhouse effect. The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind. Venus's surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism.
