Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Why is Pluto called a dwarf planet?
Is Pluto a Dwarf Planet? Because it has not cleared the neighborhood around its orbit , Pluto is considered a dwarf planet. It orbits in a disc-like zone beyond the orbit of Neptune called the Kuiper belt, a distant region populated with frozen bodies left over from the solar system’s formation.

Can we live on Pluto?
It is irrelevant that Pluto’s surface temperature is extremely low , because any internal ocean would be warm enough for life. This could not be life depending on sunlight for its energy, like most life on Earth, and it would have to survive on the probably very meagre chemical energy available within Pluto.
Is the sun a planet?
The sun and moon are not planets when you consider the objects in space they orbit. For the sun to be a planet, it would have to orbit another sun. Although the sun is in a orbit, it moves around the center of mass of the Milky Way galaxy, not another star.
