A look back at local, national and world events through Deseret News archives.
On Aug. 24, 2006, the International Astronomical Union declared that Pluto was no longer a full-fledged planet, demoting it to the status of a “dwarf planet.”
And people the world over who probably had not thought much about the solar system’s tiniest planet protested. The decision was felt most by Clyde Tombaugh, who spotted the planet in 1930 while on lookout at Lowell Observatory in Flagstaff, Arizona.
Pluto, which is in fact smaller than Earth’s moon, was quickly heralded as the ninth planet in the solar system when it was spotted Feb. 18, 1930, by Tombaugh, a young amateur astronomer stationed at Lowell Observatory.
With a diameter of 1,440 miles, Pluto is farthest from the sun. While major planets make roughly circular orbits, Pluto carves out a “sweeping ellipse.” Some wanted to call it a minor planet, others a trans-Neptunian object. Others felt it had been snubbed because it was discovered by an American amateur.
In Jaunary 2006, NASA sent its New Horizons spacecraft on humanity’s first journey to Pluto. Seven months later, it was demoted to dwarf planet.
Onboard the New Horizons craft was a small vial of Tombaugh’s ashes, per his wish.
Flagstaff of course still lays claim to Tombaugh, Lowell Laboratory and its connection to Pluto, planet or not.
