MANY thanks to the Lowell Observatory (in Flagstaff, Arizona) for including me in their wonderful “I (heart) Pluto” Festival this weekend!
Everyone had a wonderful time, including State Representative Justin Wilmoth, who is introducing a bill to the Legislature declaring that “Pluto is the State Planet of Arizona.” (As the Representative noted in his remarks, “No other state has discovered a planet!”)
(Yes, we know that Pluto is dismissed as a “planetoid” by the uninformed; (most of) the good people of Flagstaff decline to accept that designation.)
The text and image below shows (most of) the certificate the Observatory folks gave me, commemorating their naming one of “their” (as in, they discovered and registered it) asteroids after me. Quite an honor!
(28890) Gabaldon = 2000 KY65
Discovery: 2000-05-27 / LONEOS / Anderson Mesa / 699
Diana J. Gabaldon (b. 1952) is an American author. After earning a PhD in behavioral ecology and working as a university professor, she became a full time writer and is known for her bestselling Outlander series of novels. Her great-grandfather, Stanley Sykes, built the telescope used to discover Pluto.

More About Asteroid 28890 Gabaldon
28890 Gabaldon is an asteroid which orbits the Sun in the main asteroid belt between Mars and Jupiter, and it takes 4.34 Earth years for it to orbit the Sun. Its distance from the Sun is about 2.5 times the distance from the Sun to the Earth. The first diagram below shows a plot of asteroid Gabaldon looking down at an angle on the plane of the Solar System:

The orbit of the asteroid is tilted in respect to the plane of the Solar System. Below is a plot looking at the Solar System’s major planets and asteroid Gabaldon from the “side”:

Stanley Sykes Interview
Not to bore everybody with my family history, but this is kind of neat: there’s a voice recording of a 16-minute interview with my great-grandfather, Stanley Sykes, made by a researcher for a collection at Northern Arizona University. The recording is dated 1949, so the sound quality isn’t crystal-clear, but it’s pretty good. He’s telling about his arrival in Flagstaff (from England—that side of the family is from Yorkshire) in 1886, and what happened thereafter….

In 1928-1929, Stanley Sykes designed and built the telescope which astronomer Clyde Tombaugh used to discover Pluto, a magnificent scientific achievement. Almost a hundred years old now, the Pluto-discovery telescope is still in operation, and you may visit it at Lowell Observatory. More about the Lawrence Lowell 13-inch telescope.
Notes on Naming Minor Planets
The person or persons who discover a new minor planet in the solar system are given the privilege of naming it. It was members of the Lowell Observatory Near-Earth-Object Search project who discovered this asteroid at their Anderson Mesa facility in northern Arizona. It usually takes years, even decades, to verify that an object is new and orbiting the Sun, and then to officially name it.
The Working Group for Small Body Nomenclature (WGSBN) is part of the International Astronomical Union (IAU) and is responsible for assigning official names to minor planets and comets in our Solar System.
Do you like astronomy and the Solar System? Did you attend the I (heart) Pluto event on February 17? Are you looking forward to the total eclipse in the U.S.A. on April 8, 2024?
