Why is Venus hotter than Mercury?

Arabia Weather - The atmosphere of the planet Venus forms a unique mixture consisting mainly of carbon dioxide, with small percentages of nitrogen and some clouds formed from sulfuric acid.

This atmospheric composition plays a crucial role in creating global warming on the planet's surface, making it hotter than Mercury, where temperatures on its surface rise to about 482 degrees Celsius. About 48 kilometers from the planet's surface, temperatures reach between 30 and 70 degrees Celsius, and this large temperature fluctuation is very similar to what we find on the surface of Earth.

It is worth noting that the atmospheric pressure on the surface of Venus is similar to the atmospheric pressure on the surface of the Earth.

Why is Venus hotter than Mercury?

• The planet Venus is hotter than the planet Mercury due to its thicker atmosphere compared to the thin atmosphere of the planet Mercury. This difference in temperatures is due to several factors. First, Venus's gravity and the Sun's intense heat work together to preserve the planet's thick atmosphere. This is while the planet Mercury has a weaker gravity and therefore cannot maintain a good atmosphere.
• Venus' atmosphere contains elements that absorb sunlight during the day, causing temperatures on the planet's surface to rise. At night, these elements absorb infrared radiant energy from the surface, causing heat to be trapped and temperatures to continue to rise. In addition, Venus' atmosphere is ninety times thicker than Earth's , which enhances the phenomenon known as global warming and contributes to making Venus hotter than the planet Mercury, even though Venus is closer to the sun.

Facts and information about the planet Venus

1. The planet Venus is distinguished by the fact that it contains the largest number of volcanoes compared to any other planet in the solar system, with an estimated number of more than 1,600 volcanoes. In addition to this large number of volcanoes, there are also many very small volcanoes that are difficult to see with the naked eye. It is worth noting that most of these volcanoes on the surface of Venus are mostly dormant and do not spew lava regularly, but there are a few volcanoes that remain active and continue to be active.

2. Planet Venus needs 243 Earth days to complete one orbit around the Sun. Although it takes longer to complete its orbit around the Sun than on Earth, a year on Venus is shorter than a year on Earth, equivalent to only 224.7 Earth days.

3. The planet Venus is characterized by enormous air pressure on its surface, as the air pressure on its surface is equivalent to approximately 90 times the air pressure at the sea surface on planet Earth. This high atmospheric pressure is part of the extreme conditions that make Venus an uninhabitable place and very different from conditions on Earth.

4. Wind speeds in the middle cloud layer of Venus can reach 724 km/h.

5. The planet Venus, also known as Venus, takes its name from the Roman goddess of love and beauty.

6. The planet Venus is believed to have a very weak magnetic field. This is because the planet either does not have a solid inner core or its core has not cooled sufficiently.

7. The planet Venus is distinguished by its yellowish white color.

8. We sometimes know Venus as "Earth's twin" because of its similarity to Earth in terms of size and density. Venus is considered the second closest planet to the Sun, at a distance of about 108 million kilometers.

9. The surface of Venus is solid and varied. It is guaranteed by the presence of wide plains, towering volcanic mountains, and winding plateaus.
