The study’s lead author, Michael Roman, a postdoctoral fellow at the University of Leicester, said in a statement: “As we observed Poseidon in its early summer summer, we expected temperatures to rise slowly, not warmer.” “Temperature fluctuations may be related to seasonal changes in Poseidon’s atmospheric chemistry, which can change how efficiently the atmosphere cools.” “But random variability in weather patterns or even a response to the 11-year cycle of solar activity can also have an effect,” he added. With seasons lasting 40 years each, the planet Poseidon will have to escape sudden climate change, but it has cooled significantly since the start of its Austrian summer 17 years ago, according to research. According to study co-author Glenn Orton, a senior researcher at NASA’s Jet Propulsion Laboratory, “Our data cover less than half of Neptune, so no one expected to see big, rapid change.” “I think Poseidon is himself very intriguing to many of us because we still know so little about him,” Roman said. “All this shows a more complex picture of Poseidon’s atmosphere and the way it changes over time.” Read also | Lunar specimens collected by Neil Armstrong, the first man to walk on the Moon, are up for auction Poseidon is the most distant planet in the solar system. It has an extremely dynamic atmosphere. The higher clouds of Poseidon evolve so fast that the appearance of the planet can change dramatically over the days. It has the strongest zonal winds in the solar system. It has an average diameter of about 30,600 miles (49,250 km), making it four times wider than Earth. Neptune orbits the Sun more than 30 times farther from Earth at an average distance of about 2.8 billion miles (4.5 billion km). It takes about 165 Earth years to complete a single orbit around the sun, one year Poseidon. (With information from agencies)
