What is the Temperature on Venus?

Venus, often referred to as Earth's "sister planet," is a fascinating and inhospitable world with a hostile environment. If you've ever wondered about the temperature on Venus, you've come to the right place. In this article, we will explore the extreme temperature conditions that prevail on Venus and gain a better understanding of the scorching heat that characterizes this planet.

An Inferno in the Solar System

Venus is known for its blisteringly hot temperatures, making it the hottest planet in our solar system. The average surface temperature on Venus is a staggering 864 degrees Fahrenheit (462 degrees Celsius). This extreme heat is hotter than the surface of Mercury, even though Venus is further from the Sun.

Average Temperature of Venus

Venus, the second planet from the Sun, is known for its extreme temperatures, making it the hottest planet in our solar system. The average temperature on Venus is approximately 462 degrees Celsius (864 degrees Fahrenheit). This average temperature remains relatively constant throughout the planet due to the extreme greenhouse effect present in its thick atmosphere.

The atmospheric composition of Venus is predominantly carbon dioxide (CO2), with trace amounts of nitrogen and other gases. The dense atmosphere traps heat, causing a runaway greenhouse effect that contributes to the scorching temperatures on the planet's surface.

The high temperatures on Venus are further intensified by the thick atmosphere, which creates a massive greenhouse effect, trapping heat and preventing it from escaping into space. This results in a surface temperature hotter than Mercury, despite Venus being further from the Sun.

What is The Highest Temperature on Venus?

The highest temperature recorded on Venus is approximately 471 degrees Celsius (880 degrees Fahrenheit). This scorching temperature was measured by the Soviet Venera 13 spacecraft in 1982 during its descent onto the planet's surface. It's worth noting that Venus maintains extremely high temperatures throughout its atmosphere and surface, with only slight variations depending on location and time of day.

The extreme heat on Venus is attributed to its dense atmosphere composed primarily of carbon dioxide (CO2), which creates a strong greenhouse effect. The thick atmosphere traps heat from the Sun, causing a runaway greenhouse effect that results in the planet's intense temperatures. The surface of Venus is hotter than Mercury, despite Venus being further from the Sun.

The hostile environment on Venus, with its high temperatures and atmospheric pressure over 90 times that of Earth, poses significant challenges for exploration and understanding of the planet's surface and atmosphere.

Average Temperature on Planet Venus Day and Night in Fahrenheit / Celsius

Venus has an extremely hostile and uniform climate due to its thick atmosphere composed mainly of carbon dioxide with clouds of sulfuric acid. The surface temperature on Venus is incredibly hot and is roughly the same day and night because the planet's slow rotation results in very little temperature variation.

  • Average Surface Temperature on Venus: Approximately 864 degrees Fahrenheit (462 degrees Celsius).
  • Daytime Temperature on Venus:
    • During the day on Venus, which is when the Sun is illuminating its surface, temperatures can soar to an average of about 900 degrees Fahrenheit (475 degrees Celsius).
  • Nighttime Temperature on Venus:
    • At night, when Venus is on the side facing away from the Sun, temperatures don't experience a significant drop. Nighttime temperatures remain extremely high, typically around 870 degrees Fahrenheit (465 degrees Celsius).

This temperature is hotter than the surface of Mercury, the closest planet to the Sun, even though Venus is farther away. The thick atmosphere on Venus traps heat, creating a runaway greenhouse effect.

The lack of a significant day-night temperature difference on Venus is due to its extremely slow rotation, which takes about 243 Earth days for one complete rotation. Venus also has a retrograde rotation, meaning it rotates in the opposite direction to its orbit around the Sun. As a result, the planet's day and night sides experience similar extreme temperatures.

The Greenhouse Effect

The scorching temperatures on Venus are primarily caused by a runaway greenhouse effect. Venus has a dense atmosphere composed mainly of carbon dioxide (CO2), with traces of other gases like nitrogen and sulfur dioxide. This dense atmosphere traps heat radiated from the planet's surface, creating a greenhouse effect that intensifies the temperature.

The thick layer of carbon dioxide in Venus' atmosphere acts as a blanket, preventing the escape of heat into space. The trapped heat leads to a significant rise in temperature and creates the extreme conditions found on the planet.

Superrotation and Atmospheric Circulation

Another contributing factor to the high temperatures on Venus is its unique atmospheric circulation. The planet experiences an atmospheric phenomenon known as superrotation, where the atmosphere rotates much faster than the planet itself.

This rapid rotation results in fierce winds blowing at high speeds, circulating the heat and contributing to the overall temperature increase. The superrotation of the atmosphere on Venus creates a continuous cycle of heat distribution, further exacerbating the extreme temperatures.

Altitude and Temperature Variations

While the surface of Venus is incredibly hot, the temperature decreases with increasing altitude. As you move higher into the atmosphere, the temperatures gradually become cooler due to the decrease in pressure and the presence of different atmospheric layers.

At around 30 to 40 miles (50 to 65 kilometers) above the surface, the temperature reaches a relatively mild 68 to 122 degrees Fahrenheit (20 to 50 degrees Celsius). This region, known as the mesosphere, experiences temperatures comparable to Earth's surface, making it the most Earth-like area in Venus' atmosphere.

Challenges for Exploration

The extreme temperature conditions on Venus pose significant challenges for spacecraft and potential human exploration. The scorching heat, corrosive atmosphere, and intense pressure make it one of the most hostile environments in our solar system.

Despite these challenges, space agencies like NASA and other international entities continue to study Venus and develop innovative technologies to explore its surface and atmosphere. Future missions, such as NASA's proposed VERITAS and DAVINCI+ missions, aim to further investigate Venus' temperature, geology, and atmospheric conditions, providing valuable insights into this mysterious planet.


Venus, with its searing temperatures and intense greenhouse effect, showcases the extreme diversity of conditions within our solar system. Its average surface temperature of 864 degrees Fahrenheit (462 degrees Celsius) is a testament to the inhospitable environment that exists beyond our home planet.

Understanding the temperature on Venus not only expands our knowledge of planetary science but also ignites our curiosity about the intricacies of the universe. The scorching heat on Venus serves as a reminder of the delicate balance that sustains life on Earth and the importance of studying other celestial bodies to better comprehend our place in the cosmos.
