Important facts of Venus

Venus location in the Solar System:

Venus is the second planet from the Sun in the Solar System.  Information available so far, there is no life on Venus as the surface temperature is 867 degree Fahrenheit (464 degree Celsius).  No any known life can sustained in that temperature.

The average distance of the Venus from the Sun is about 108.2 million kilometers (67.62 million miles)

This distance is equivalent to 0.72 Astronomical Unit.

Venus is named after the Roman goddess of love and beauty. Venus is the brightest natural object in Earth's night sky after the Moon. Venus can cast shadows and can be, on rare occasion, visible to the naked eye in broad daylight.  Venus lies within Earth's orbit, and so never appears to venture far from the Sun, either setting in the west just after dusk or rising in the east a little while before dawn.

Venus Equatorial Diameter is 12104 km.

Moons of Venus:

Venus is a Moonless planet.

Five Important facts of Venus

Venus Rotation & Revolution

 1.     The average distance of the Venus from the Sun about 108.2 million kilometers (67.62 million miles)

2.     Venus rotates clockwise axis. Venus is the only planet who rotates in clockwise direction.

3.     The Venus takes 116 Day 18 Hrs. 0 Minute to complete one rotation.

        The Venus rotates Clockwise on its axis at a speed of 6.52 km/h (1.81 m/s)

4.     Venus takes 224.701 Earth day (0.615198 Earth Year) days to complete one revolution of the Sun.  

        The Venus revolves around the Sun and at a speed of 35.02 km/s or 126,072 km/hour

5.     The Venus's axis tilts to 2.64 degree at equator

Physical characteristics Venus

Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth.  It is similar to Earth in size and mass, and is often described as Earth's "sister" or "twin”. The diameter of Venus is 12,103.6 km (7,520.8 miles) only 638.4 km (396.7 mi) less than Earth's and its mass is 81.5% of Earth's. Conditions on the Venusian surface differ radically from those on Earth because its dense atmosphere is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen.  The surface pressure is 9.3 Mpa (93 bar) and the surface temperature is 737 K (464 °C or 867 °F), above the critical points of both major constituents and making the surface atmosphere a supercritical fluid.

Surface Geology of Venus

Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km (60 mi) 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. Earth's oceanic crust is continually recycled by downward movement of the edge at the boundaries of tectonic plates, and has an average age of about a hundred million years, whereas the Venusian surface is estimated to be 300–600 million years old.

Several lines of evidence point to on-going volcanic activity on Venus. Sulphur dioxide concentrations in the atmosphere dropped by a factor of 10 between 1978 and 1986, jumped in 2006, and again declined 10-fold.  This may mean that levels had been boosted several times by large volcanic eruptions. It has also been suggested that Venusian lightning (discussed below) could originate from volcanic activity (i.e. volcanic lightning). In January 2020, astronomers reported evidence that suggests that Venus is currently volcanically active.

Atmosphere of Venus

Venus has an extremely dense atmosphere composed of 96.5% Carbon Dioxide, 3.5% Nitrogen both being supercritical fluids at surface, and traces of other gases including Sulphur Dioxide. The mass of its atmosphere is 93 times that of Earth's, whereas the pressure at its surface is about 92 times that at Earth's—a pressure equivalent to that at a depth of nearly 1 km (5⁄8 mi) under Earth's oceans. The density at the surface is 65 kg/m3, 6.5% that of water or 50 times as dense as Earth's atmosphere at 293 K (20 °C; 68 °F) at sea level.  The CO2-rich atmosphere generates the strongest greenhouse effect in the Solar System, creating surface temperatures of at least 735 K (462 °C; 864 °F).  This makes Venus' surface hotter than Mercury's, which has a minimum surface temperature of 53 K (−220 °C; −364 °F) and maximum surface temperature of 700 K (427 °C; 801 °F),  even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance. This temperature is higher than that used for sterilization.


No evidence of life has been found on Venus.
