What Is The Planet Venus? Complete Details


What Is The Planet Venus?: Venus is the second planet in our Solar System and is very similar to Earth in size, mass, density, and volume. It was formed from the same nebula as the earth, but they have big differences.


Its name was given in honor of the Roman goddess of love and beauty, in fact, it is the only planet named after a woman, and it was named so because it shone more than the other planets known to ancient astronomers.


We cannot see the surface of Venus from Earth, because it is covered with thick clouds. However, space missions to Venus have shown that its surface is covered with craters, volcanoes, mountains, and large lava plains.

  • Distance to the sun:  108.2 million kilometers
  • Gravity:  8.87 m / s²
  • Day length:  116 days and 18 hours
  • Orbital period:  225 days

What is the planet, Venus?

The planet Venus is the second planet that we can locate within the Solar System, very similar to the earth in terms of size, mass, density, and volume, and was created from a nebula just like the earth.

Venus characteristics:

  • It is the second planet in the Solar System in distance from the Sun, and the third in size, after Mercury and Mars.
  • Its name was given in honor of the Roman goddess of love.
  • It is also known as ” the twin ” of the Earth because they are very similar in size.
  • The planet’s diameter is approximately 12,100 kilometers at the equator, approximately 644 kilometers, smaller than that of Earth.
  • It turns on itself slowly by means of a retrograde movement, in the same sense as the hands of the clock.
  • Its orbit is the roundest of all in the Solar System.
  • The surface of Venus is made up of igneous rock with very few meteorites and crater impacts.


According to historians and scientists, Venus has formed approximately 4 billion years ago. After its formation, it was hit by abundant excess material so it overheated from its interior and separated into layers. Then the planet cooled down again and the crust started to get hard. This rigidity of its crust prevented a continental drift from occurring.


There is very little data regarding the geochemistry and internal structure of Venus, however, it is known to have a core, mantle, and planetary crust. The core of Venus is made up of an inner core and an outer shell. The outer part is composed of iron and nickel, both in a liquid state.

Its inner core is made up of the same materials but in a solid state. In its mantle, rocky silicates and metallic oxides can be found. Its crust is very thin, barely 20 kilometers, and is composed of graphite and basalt earth which is very rich in silica and ferromagnesian.

The atmosphere of Venus:

Its atmosphere is very hot and dense. It is composed mainly of carbon dioxide and very thick clouds composed of sulfuric acid that cover the entire planet. The atmosphere is responsible for trapping the little amount of energy that the sun provides and that reaches the surface.

This is known as a type of effect gas and causes the surface of the planet and the atmosphere of Venus to be the places hot in the solar system. The atmosphere is made up of nitrogen, carbon dioxide, nitrogen, and very little carbon monoxide, argon, sulfur dioxide, and water vapor.

Magnetic field:

For a planet to have a magnetic field it must be formed by a liquid ferrous core due to the rotational movements that it produces when it melts, although it has an iron core, the planet does not register any presence of such a field due to the slow ability of the rotary movement.

Rotation and translation of Venus:

The rotation of Venus happens in the opposite direction to that of the earth, so that on Venus the sun rises to the west and sets to the east side.

A normal day on Venus lasts more than a year, this is because its translation movement lasts 225 Earth days and its rotation lasts 243. This more simply explained means that a day on Earth lasts 24 hours, but on Venus, a day lasts 243 Earth days.

Satellites of venus:

To date, no satellites have been recorded on Venus.


The planet’s temperature is extremely high, and it is considered the hottest in the Solar System, reaching temperatures of up to 499 ° C. It is the second closest planet to the sun and has the hottest atmosphere even of Mercury.


Some curiosities of this planet are:

  • There is no difference between the temperature during the day and at night.
  • Its size is just a little smaller than the earth’s.
  • Its atmosphere is composed mainly of large amounts of carbon dioxide.
  • In its clouds, there is constant acid rain, the most corrosive in the Solar System.
  • Its surface is full of craters and volcanoes with continuous activity.
  • A day on Venus lasts 243 Earth days.
  • It can be observed from the ground at noon.
  • It has no moon.
