Your Complete Guide To Pluto
Learn everything there is to know about the oddball of
our solar system.
Understanding Pluto
In 1930, an American astronomer named Clyde Tombaugh, working at the Lowell Observatory, saw something new in the night sky: a ninth planet. The family was growing, and everyone was happy. But in 2006, the IAU (International Astronomical Union) decided to kick it out, demoting it to a 'dwarf planet.' Although it was reclassified, it still remains a favorite and iconic part of our solar system.
How Much Do You Know About Pluto?

How Pluto Got Famous
In July of 2015 NASA’s New Horizons spacecraft sent back the first high resolution images of Pluto the world had ever seen. Everyone saw Pluto for what it was; an icy world of mountains, glaciers, and ice volcanoes. The Internet went wild with memes, excitement, and debates on whether Pluto should be a planet. This moment not only expanded our understanding of Pluto but also reignited public fascination with the mysteries of our solar system. This event helped us learn more about Pluto and made people excited about the mysteries of our solar system again.
Could Pluto Be a Planet Again?
Some astronomers argue that the IAU’s definition of a planet is flawed and that Pluto—and other dwarf planets—should be reinstated as full-fledged planets. In 2017, a team of NASA scientists proposed a new definition that would classify Pluto as a planet again, along with more than 100 other objects in the solar system. The debate continues.
