Summer on Neptune lasts for 40 years, but the temperature is minus 328°F.
Neptune is the most distant planet in the solar system, around 30 times farther from the sun than Earth is. Just like every other planet orbiting the sun, Neptune has four distinct seasons: spring, summer, fall and winter. However, because Neptune takes around 165 years to orbit the sun, each of these seasons lasts around 40 years. Neptune’s southern hemisphere has been experiencing summer, the period when it is tilted toward the sun, since 2005.
