SUMMER SPECIAL: In 1930, the elusive Planet X — later named Pluto — was introduced to the world to much fanfare as the solar system’s ninth planet. So why was it rejected again, just 76 years later?
When US astronomer Clyde Tombaugh first found Pluto on the edge of the solar system, he joined the small and exclusive club of planet discoverers. The world was, frankly, over the moon about the newest, littlest planet. They loved it so much, even Mickey Mouse named his dog after it.
Then along came Pluto’s biggest fan, Mike Brown. His love for the little planet would eventually lead him into a career in astronomy — and would spell doom for the solar system’s coolest (literally — it can get down to -240C) member.
Find out exactly how Pluto became the little planet that couldn’t in this special summer edition of Ratbags & Roustabouts.
