It takes about 6 minutes and 20 seconds for sunlight to reach the earth. It takes about four hours for that light to reach the farthest planet in the solar system. The last planet in the solar system, Neptune, is four billion kilometers away from the Sun. That Neptune is currently undergoing a unique transformation.
Neptune has been widely observed for two decades. A more complete picture of Neptune’s temperature change than ever before has been released. The planet is going through a dramatic drop in its atmospheric temperature. The average temperature in Neptune’s stratosphere dropped by about 6 degrees Celsius between 2003 and 2016.
According to scientists, this change in temperature is undesirable. According to the research article, the observation of heat-infrared wavelengths outside the visible light spectrum depends on the sensation of heat emitted from the planet’s atmosphere.
Due to its greater distance from the Sun and its greater inclination toward the Neptune axis, the seasons feel like Earth. This planet takes about 175 years to complete an orbit around the sun. The seasons of the planet are very long. Each season lasts more than 40 years. Source: Euro News.
