Overview of Surface Much of the surface of Venus appears to be rather young. The global data set from radar imaging reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years. There are two continents, which are large regions several kilometers above the average elevation.

Surface features of Venus Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) that preserves geologic structures for long periods of time.

Observations and explorations of Venus As one of the brightest objects in the sky, Venus has been known since prehistoric times and as such has gained an entrenched position in human culture. It is described in Babylonian cuneiformic texts such as the Venus tablet of Ammisaduqa, which relates observations that possibly date from 1600 BC.

1. Which one of the following is a green house gas? Carbon dioxide 2. The tallest living tree is Sequoia 3. Atmosphere: The surface temperature of Venus is around 890 degrees F, the hottest average temperature in the Solar System. This is due to a runaway greenhouse effect. The atmosphere of Venus is composed of 97% CO2, 2% N2 and less than 1% of O2, H2O and CH4 (methane).Since CO2 is a major greenhouse gas, the radiation from the Sun is trapped in the atmosphere of Venus producing an extremely high surface temperature.he atmosphere of Venus is composed of 97% CO2, 2% N2 and less than 1% of O2, H2O and CH4 (methane).

- Venus orbits the sun in approximately 225 Earth days. (224.70069 days) Strange as it may seem, Venus rotates so slowly that a day on Venus is longer than its year. It take … s Venus about 243 Earth days to spin once on its axis.The slow rotation is also in a retrograde (clockwise) direction, from east to west.anned missions such as the Apollo trip to the Moon would require 1 to 3 months at a minimum, to reach the planet's orbit. At the maximum velocity of any current spacecraft, a direct flight would require between 30 and 120 days, depending on Venus's position in its orbit.

- Venus on the other hand with it's much thicker atmosphere holds all the heat it gets. The heat the atmosphere traps is called the greenhouse effect. If Venus did not have an atmosphere the surface would be -128 degrees Fahrenheit much colder than 333 degrees Fahrenheit, the average temperature of Mercury.

- One concept that is used for time on Venus is the longitudinal noon, which establishes 360 divisions of rotational time to the 1.92 solar days that exist during the Venusian year (225 Earth days). Of course, the Sun would never actually be visible on the surface.

- • A day on the surface of Venus (solar day) would appear to take 117 Earth days • A year on Venus takes 225 Earth days. http://space-facts.com/venus/ A Venusian solar day lasts 117 Earth days, versus 225 Earth days to complete an orbit, so there’s your 1.92 ratio.

Planet Venus Facts: A Hot, Hellish & Volcanic Planet Six mountainous regions make up about one-third of the Venusian surface. One mountain range, called Maxwell, is about 540 miles (870 km) long and reaches up to some 7 miles (11.3 km) high, making it the highest feature on the planet. Venus also possesses a number of surface features unlike anything on Earth.

Orbit and Rotation of Venus It takes Venus 224.65 days to complete its orbit, which means a year on Venus is approximately 224.65 Earth days. While all planets’ orbits are elliptical, Venus’ orbit is the only one which is closest to circular. Its eccentricity is less than 0.01.

Venus This makes the Venusian surface hotter than Mercury 's, which has a minimum surface temperature of 55 K (−220 °C) and maximum surface temperature of 695 K (420 °C), even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance.

However, unlike the Earth or Venus, the atmosphere is very thin, about 1% the mass of Earth's atmosphere. Its composition is 95% CO2, 3% N2, 2% Ar and less than 1% O2.

How Hot is Venus? At the surface, the atmosphere presses down as hard as water 3,000 feet beneath Earth's ocean. The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C). Temperatures are cooler in the upper atmosphere, ranging from (minus 43 C) to (minus 173 C). Balmy all year-round.

Atmosphere of Venus The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is  740 K (467 °C, 872 °F), and the pressure is 93 bar (9.3 MPa), roughly the pressure found 900 m (3,000 ft) underwater on Earth.

Venus Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows.enus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km across. The only volcanic complex of this size on Earth is the Big Island of Hawaii. This is not because Venus is more volcanically active than Earth, but because its crust is older.

- Due to Venus being a goddess of womanhood, all of the features on the planet, except for one, are named after women. The main craters, for example, are named after influential women that existed during various times. One of them is the famous ballerina, Anna Pavlova, who lived from 1881 to 1931.

Venus's atmosphere The average surface pressure on Venus is about 90 times that on Earth (almost as much pressure as you would experience at a depth of a kilometre in the Earth’s oceans), and the atmosphere is 96% carbon dioxide, 3.5% nitrogen, 0.015% sulphur dioxide, 0.01% water vapour and 0.007% argon.

- by Fraser Cain on August 6, 2009. The period of rotation for Venus is 243 days. In other words, Venus takes 243 days to turn once on its axis so that the stars are in the same position in the sky. That seems like a long time, and it is. Especially when you consider that a year on Venus only lasts 224.7 days.
