Unlike the other planets Mercury has a huge range in surface temperature due to lack of atmosphere. At the equator, the surface temperature on Mercury can range from 100K (-173'C) to 700K (430'C).**temperature at the 1.0 bar pressure level

Varies from planet to planet, of course, and from point to point ON each planet. The sunlit side of Mercury can be as hot as 400 degrees C, while the dark side can be -200C. Venus is actually hotter, at 470C. The outer gas giants are quite frigid, understandable given their distance from the Sun.
Mercury: 430°C Venus: above 450°C Earth: 15°C Mars: -60°C Jupiter: -145°C Saturn: -178°C Uranus: -224°C Neptune: -214°C
All of the planets orbit the sun in the plane of the ecliptic (also known as the ecliptic plane).
Venus is the hottest planet in our solar system, with surface temperatures reaching up to 870 degrees Fahrenheit (465 degrees Celsius). Mercury, the closest planet to the Sun, also experiences extreme temperature variations, with surface temperatures ranging from -290 degrees Fahrenheit (-180 degrees Celsius) to 800 degrees Fahrenheit (430 degrees Celsius).
Neptune has a surface more similar to the inner planets than to the other outer planets. It is primarily composed of rock and ice, similar to the composition of the inner planets, whereas the other outer planets are predominantly gas giants.
the sun
Mercury is the planet closest to the sun in our solar system. Its proximity to the sun causes its surface temperature to be extremely hot, and its orbit is the fastest of all the planets.
The temperature on the surface of some planets can be higher than Earth's surface due to factors like proximity to the sun, composition of the atmosphere (greenhouse gases), and internal heat sources (volcanic activity). These factors can contribute to trapping heat and raising surface temperatures beyond what we experience on Earth.
