the world’s astronomers have concluded two years of work defining the lower end of the planet scale - what defines the difference between “planets” and “solar system bodies”. if the definition is approved our solar system will consist of 12 planets: mercury, venus, earth, mars, ceres, jupiter, saturn, uranus, neptune, pluto, charon and 2003 ub313. the three new proposed planets are ceres, charon (pluto’s companion) and 2003 ub313.
in this artist’s impression (above) the planets are drawn to scale, but without correct relative distances.
