The solar system’s hottest planet is Mercury. It is closest to the sun and has no atmosphere to protect it from the sun’s heat. The average temperature on the surface of Mercury is 800 degrees Fahrenheit. However, the temperature can range from -279 degrees Fahrenheit to 801 degrees Fahrenheit.

Hottest Planet In The Solar System
The hottest planet in the Solar System is Venus. It is the second closest planet to the Sun and has an average temperature of 864°F, which is significantly higher than any other planet in the Solar System. This is due to its thick atmosphere which is made up of mostly carbon dioxide and nitrogen, trapping heat close to the surface. It is also the second-brightest natural object in the night sky and is the only planet in the Solar System that rotates clockwise. Venus is also covered in an incredibly thick layer of clouds made up of sulfuric acid, hiding its extremely hostile surface from view. All of these factors combine to make Venus the hottest planet in the Solar System.
Introduction to the hottest planet in the Solar System
Welcome to our introduction to the hottest planet in the Solar System! This incredibly scorching planet is none other than Venus, the second planet from the Sun.
Venus is the hottest planet in the Solar System due to its dense atmosphere which is composed primarily of carbon dioxide with a few other trace elements. This thick atmosphere traps the Sun’s energy and creates what is known as a ‘greenhouse effect’, causing the planet to heat up to a staggering 462°C. This is more than twice as hot as the hottest temperature ever recorded on Earth, making Venus the hottest place in the entire Solar System.
The surface of Venus is composed of basaltic rock which has been heavily eroded over time. The planet’s surface is also covered in craters, channels, and gullies, indicating a history of volcanic activity. These features are further enhanced by the planet’s thick atmosphere, which reduces visibility and makes it difficult to observe the surface from a distance.
The atmosphere of Venus is also extremely turbulent and turbulent winds whip around the planet at speeds of up to 250 mph. The winds are so strong that they can cause objects to move across the planet’s surface, creating strange patterns and shapes. These winds, combined with the extreme temperatures, make Venus a difficult planet to explore.

Despite its hostile environment, Venus has been studied extensively by scientists for decades. In fact, it was the first planet after Earth to be explored with a spacecraft. The Soviets’ Venera probes were the first to reach Venus and they sent back valuable data about the planet’s atmosphere and surface.
Today, we still continue to explore Venus in search of new discoveries. In fact, there are several missions in the works that will send spacecraft to the planet. The European Space Agency’s Venus Express mission will be the first to send a probe to the planet’s atmosphere and surface.
So there you have it – a brief introduction to the hottest planet in the Solar System, Venus. We hope this article has given you a better understanding of the planet and its incredible features.
Explanation of why the planet is the hottest
The hottest planet in the Solar System is Venus, with an average temperature of over 462°C. This is due to a combination of factors, including its proximity to the Sun and its thick atmosphere.
For starters, Venus is the second planet from the Sun. This means that it receives more energy from the Sun than any other planet in the Solar System. On top of this, Venus has an exceptionally thick atmosphere made up of mostly carbon dioxide, which traps that energy and keeps it from escaping. This is known as the “greenhouse effect” and is the same phenomenon that makes Earth’s climate much milder than it would otherwise be.
On Venus, this greenhouse effect is so strong that it raises the surface temperature of the planet to almost 500°C. This is significantly higher than any other planet in the Solar System. Much of this heat is then trapped in the atmosphere, resulting in an average temperature of over 462°C.
Another factor that contributes to the extreme heat on Venus is its slow rotation. While Earth has a day that lasts 24 hours, the day on Venus lasts for 243 Earth days. This means that the Sun is always at its zenith when it is visible from the planet. This creates a never-ending day that further contributes to the planet’s intense heat.

All of these factors combine to make Venus the hottest planet in the Solar System. Its proximity to the Sun, thick atmosphere, and slow rotation all contribute to the extreme temperatures on the planet’s surface.
Comparison of the temperature of the hottest planet to other planets
When it comes to the temperature of the planets in our Solar System, none can compare to the hottest planet of them all – Venus. The average temperature on Venus is a scorching 462°C (864°F), making it the hottest planet in the entire Solar System. To put this temperature into perspective, the hottest planet in our Solar System is around 8 times hotter than Mercury, the planet closest to the Sun.
In comparison to other planets in the Solar System, Venus stands out due to its proximity to the Sun and its dense atmosphere. Venus is the second closest planet to the Sun, with an average distance of 108.2 million km. This puts it almost twice as close to the Sun as Mercury, which has an average distance of 57.9 million km. Additionally, Venus’ thick atmosphere is composed of 96.5% carbon dioxide, which traps the heat from the Sun and prevents it from escaping. This is why Venus is so much hotter than Mercury, despite being almost the same distance from the Sun.
The next hottest planet after Venus is Earth, which has an average temperature of 15°C (59°F). This is almost 30 times cooler than Venus, despite being only slightly farther away from the Sun. This is due to Earth’s atmosphere, which is composed of 78% nitrogen and 21% oxygen, which is far less dense than Venus’ carbon dioxide-rich atmosphere. Additionally, Earth’s atmosphere contains a layer of ozone, which helps to protect the planet from harmful radiation from the Sun.
After Earth, the remaining planets in our Solar System become drastically cooler. Mars, the fourth planet from the Sun, has an average temperature of -55°C (-67°F). Even farther out, the gas giants of our Solar System, such as Saturn and Jupiter, have average temperatures of -178°C (-288°F) and -145°C (-233°F), respectively. This is due to their great distance from the Sun and their lack of a dense atmosphere.
In conclusion, the temperature of the hottest planet in our Solar System, Venus, is drastically hotter than the other planets in our Solar System due to its proximity
Conclusion
The planet that is the hottest on the sun is Mercury. Mercury has an average temperature of 480 degrees Fahrenheit, which is much higher than any other planet in the solar system. Mercury is also the closest planet to the sun, which makes it the most exposed to the heat.
