California Assembly Bill HR 36 Relative to Pluto's planetary status

WHEREAS, Recent astronomical discoveries, including Pluto's oblong orbit and the sighting of a slightly larger Kuiper Belt object, have led astronomers to question the planetary status of Pluto; and

WHEREAS, The mean-spirited International Astronomical Union decided on August 24, 2006, to disrespect Pluto by stripping Pluto of its planetary status and reclassifying it as a lowly dwarf planet; and

WHEREAS, Pluto was discovered in 1930 by an American, Clyde Tombaugh, at the Lowell Observatory in Arizona, and this discovery resulted in millions of Californians being taught that Pluto was the ninth planet in the solar system; and

WHEREAS, Pluto, named after the Roman God of the underworld and affectionately sharing the name of California's most famous animated dog, has a special connection to California history and culture; and

WHEREAS, Downgrading Pluto's status will cause psychological harm to some Californians who question their place in the universe and worry about the instability of universal constants; and

WHEREAS, The deletion of Pluto as a planet renders millions of text books, museum displays, and children's refrigerator art projects obsolete, and represents a substantial unfunded mandate that must be paid by dwindling Proposition 98 education funds, thereby harming California's children and widening its budget deficits; and

WHEREAS, The deletion of Pluto as a planet is a hasty, ill-considered scientific heresy similar to questioning the Copernican theory, drawing maps of a round world, and proving the existence of the time and space continuum; and

WHEREAS, The downgrading of Pluto reduces the number of planets available for legislative leaders to hide redistricting legislation and other inconvenient political reform measures; and

WHEREAS, The California Legislature, in the closing days of the 2005-06 session, has been considering few matters important to the future of California, and the status of Pluto takes precedence and is worthy of this body's immediate attention; now, therefore, be it

Resolved by the Assembly of the State of California, That the Assembly hereby condemns the International Astronomical Union's decision to strip Pluto of its planetary status for its tremendous impact on the people of California and the state's long term fiscal health; and be it further

Resolved, That the Assembly Clerk shall send a copy of the resolution to the International Astronomical Union and to any Californian who, believing that his or her legislator is addressing the problems that threaten the future of the Golden State, requests a copy of the resolution.

That California resolution makes far more sense than the nonsense adopted by four percent of the IAU, most of whom are not planetary scientists. Their decision was immediately rejected by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA's New Horizons mission to Pluto.

The IAU definition makes no sense for two reasons. One, it states that dwarf planets are not planets at all. That is like saying a grizzly bear is not a bear. It is also inconsistent with the use of the term "dwarf" in astronomy, where dwarf stars are still stars, and dwarf galaxies are still galaxies.

Second, the IAU definition classifies objects solely by where they are while ignoring what they are. If Earth were in Pluto's orbit, according to the IAU definition, it would not be a planet either. A definition that takes the same object and makes it a planet in one location and not a planet in another is simply unusable.

The controversy could easily be solved if the IAU amends its 2006 resolution to make dwarf planets a subcategory of the broader term "planet."
