Our Universe is an amazing place where different planets occupy a small place. The Earth and Venus are among the eight largest planets that have found a place in the mystical Solar System. All the planets move round this great ball of fire, the Sun, as we know it, and among them, four rocky planets namely the Earth, Venus, Mercury and Mars are the closest to the Sun.
Fact 1 Description Of The Planet Earth
We all know that the Earth’s surface is mostly covered with water (3/4 water and ¼ land) for which it resembles a blue marble from above with patches of brown, green, yellow and white. These colorful areas signify land, fields, deserts and snow-capped mountains. The earth, while rotating on its own axis in 24 hours, revolves round the sun. This journey takes 365 and1/4 days to complete one round and the seasons change according to the position of the places that are tilted towards the sun or are away from the sun.
Fact 2 About The Planet Venus
Venus is the brightest planet that occupies the second place near the sun. It is named after the Roman Goddess of beauty and love. It is however the hottest planet in the Solar system. The heat of the sun is trapped in the dense atmosphere of the planet that makes the temperature rise to 870 degrees Fahrenheit although it is not very close to the sun. It is difficult to survive for more than a few hours in this planet.
Fact 3 Earth And Venus Are Called Twins
Often Venus and the Earth are called twins. This is because some of the characteristics of these two planets are similar. They are of the same size, density, gravity, mass as well as composition. Yet they are not the same in many other respects for which the Earth is inhabitable while Venus is not. The heat in the atmosphere is so intense that it can even melt down lead.
Fact 4 Differences Between Earth And Venus
There are quite a few distinctive features that show the difference between these two planets namely Earth and Venus.
- Difference in the composition of atmosphere: The atmosphere of Venus consists of carbon dioxide, clouds made up of sulfuric acid. Earth comprises of nitrogen and oxygen that help us to breathe and live.
- The weight of the atmosphere or the mass is the highest in Venus. It exerts 90 times surface pressure as compared to Earth.
- The surface temperature on Earth is only 100 degrees Fahrenheit and is lesser than Venus where the temperature rises to 870 degrees Fahrenheit. Hence there is life on Earth. Moreover, Earth is ¾ covered by water and only ¼ by land whereas traces of water is seen in Venus.
- Difference in magnetic field: Venus also has a magnetic field like the Earth. But is weaker in comparison to the Earth.
- Difference in magnetic field: The movement of the planetary core along with the convection arising from the same area creates the magnetic field of the Earth. But in the case of Venus it is created by the interaction of solar wind and ionosphere. The core of Venus is liquid in form and rotates like the earth’s core.
- Difference in movement: The earth rotates on its axis in a counter clockwise direction and so we see the sun rising in the east and setting in the west, while Venus rotates clockwise. Hence sunrise and sunset appears in the opposite directions.
- Variation in speed: The Earth rotates faster and so Venus has longer days as compared to the Earth.
- Presence of moons: Earth has a moon that revolves round it but Venus has none.
