Voyager program
In 2013, NASA announced that Voyager 1 had  left the solar system (Heliosphere) on 25 August 2012. It is the first man-made object to enter interstellar space. In 2018, NASA announced that Voyager 2 had reached the heliopause on 5 November of that year.  Both of them are now in travelling in the interstellar space. Voyager spacecraft are the farthest spacecraft from Earth. On February 17, 1998, Voyager 1 passed the first spacecraft that completed the 1st mission to Jupiter, Pioneer 10 in the distance to the Sun at 70 AU (6.5 billion miles, 10.5 billion km) from it as the farthest spacecraft from the Sun. Voyager 2 overtook Pioneer 10 in the distance to the Sun at 133.92 AU (12.447 billion miles, 20.03 billion km) from it on July 18, 2023 as the 2nd farthest spacecraft from the Sun.
