Pluto was reclassified as a dwarf planet by the International Astronomical Union on August 24, 2006.
One article marks the anniversary with five facts about Pluto, including its name, moons, distance from the Sun, and orbital behavior.
Another argues that the reclassification highlights the diversity of the solar system rather than diminishing Pluto.
That piece says keeping Pluto as a dwarf planet avoids having to classify dozens of similar distant bodies as planets.
Why it mattersIt marks a major milestone in modern astronomical history and public fascination with planetary science.
