Naming the Asteroids

I wrote earlier about 3200 Phaethon, the asteroid that causes us to see the Geminid meteor showers that appear in December. The first asteroids to be discovered were named for characters from classical mythology, such as Ceres and Juno. But the International Astronomical Union (IAU) now regulates the naming of asteroids, and names are no longer restricted to only mythological characters.

The naming of heavenly bodies and celestial objects is quite interesting. An article from the Open University, says that an asteroid is not awarded a name until it has been observed long enough for its orbit to be determined with a fair degree of precision, which may take several years.

The “permanent designation” is a rather boring number issued in strict numerical sequence, but the discoverer is invited to suggest a name for approval by a special committee of the International Astronomical Union.

As we begin to be able to land on these asteroids, the idea of mining asteroids becomes less science-fiction and more like an actual space industry.

There are some much more unusual or whimsical names.

7758 Poulanderson is named after a science fiction author Poul Anderson.

I quite like that object 8749 is named "Beatles" after best known of all rock bands. In addition to 8749 Beatles, there are four consecutively numbered minor planets named after the individual members of The Beatles:

• 4147 Lennon (John Lennon)
• 4148 McCartney (Paul McCartney)
• 4149 Harrison (George Harrison)
• 4150 Starr (Ringo Starr)

The Beatles are not alone in being pop musicians with celestial objects bearing their names. Elvis, Frank Zappa, Jerry Garcia, the Rolling Stones (which seems appropriate for these rocks), Frank Sinatra, George Gershwin, Led Zeppelin, Procol Harum, Bruce Springsteen and many others are all floating out there.

And fictional names also get their place in space. From Beowulf to Bilbo Baggins, Sherlock Holmes and Mr. Spock.

The number 5460 asteroid has the name Tsenaat'a'i which means “flying rock” in the Navaho language.

A name of pure invention, and some difficulty to pronounce at first glance, went to object 2037. It is named Tripaxeptalis. It is pronounced to sound like tri Pax sept Alice. The etymology of that is that its permanent designation is three times (tri) that of asteroid 679 Pax and seven times (sept) that of number 291 Alice.
