Neptune is one of the coldest planets in the solar system, to which only 1/900 of the heat received by the The Sun. However, ESO astronomers have seen that it has a hot part: the south pole. Specifically, it is 18ºC warmer than the average (the average temperature is -320ºC). This is due to the tilt and orbit of the axis, the south pole has been tilted towards the Sun for 40 years, which has caused warming.
