Space probe Entered orbit around dwarf planet Ceres in early 2015. Currently orbiting Ceres as of February 2017. First probe to Jupiter without atomic batteries, launched August 8, 2011. Chang'e 2 was deployed to orbit the Moon, visit Sun–Earth L2 Lagrangian point, and make a flyby of asteroid 4179 Toutatis. Along with "Pioneer 10", "Pioneer 11", and its sister space probe "Voyager 2", "Voyager 1" is now an interstellar probe. "Voyager 1" and "2" have both achieved solar escape velocity, meaning that their trajectories will not return them to the Solar System. Examples of space probe imaging telescope/cameras (focused on visible spectrum).
