Neptune's surface temperature is estimated at minus 353 degrees Fahrenheit. The surface temperature varies based on where the planet is in its rotation, and different poles are continuously exposed to the Sun's heat.
The seasons on Neptune can cause the surface temperature at the poles to vary by as much as 50 degrees Fahrenheit. Similar to other planets, the temperature on Neptune increases as the atmospheric pressure rises toward the core of the planet. At its center, the temperature can reach 9,000 degrees Fahrenheit.The disparity of temperature between the planet's surface and its core is the cause of Neptune's violent wind storms.
