On this day 42 years ago, June 13, 1983 (May 3, 1983, the Pioneer 10 probe flew out of the orbit of Neptune. Pioneer 10, launched by the National Aeronautics and Space Administration (NASA) in 1972, exited the orbit of Neptune on June 13, 1983. Because Pluto's orbit is a large ellipse, its orbit will be within the orbit of Neptune for the next 17 years. Pioneer 10 will be the first man-made object to leave the solar system. Over the past 11 years, the 290-kilogram detector has received a total of 98900 command signals from Earth; 126 billion information units of data and photos are sent back to Earth. The beautiful picture of Jupiter is taken by it and sent back to the earth. Pioneer 10 left the solar system at a speed of 49198 kilometers per hour. When it leaves Neptune, it is more than 4.53 billion kilometers away from the Sun. Its electronic system is powered by a radioisotope thermoelectric source system. According to the Ames Research Center, the data sent back by Pioneer 10 will take 10 years to study and analyze, even with advanced computers, it will take years.
