Kameny, who earned a doctorate in astronomy at Harvard University, was an astronomer with the U.S. Army Map Service in the 1950s but was fired from his job for being gay. He contested the firing all the way to the Supreme Court and later organized the first gay rights protests outside the White House, the Pentagon and in Philadelphia in the 1960s.
Kameny died last year at age 86.
When astronomer Gary Billings read Kameny's obituary, he consulted with others in the astronomy world. They decided to submit a citation to the Paris-based International Astronomical Union and the Minor Planet Center in Cambridge, Mass., seeking to designate Minor Planet 40463 as Frankkameny.
It's located in the asteroid belt, orbiting between Mars and Jupiter. The Kameny asteroid is visible through a telescope and was first discovered in 1999 using long-exposure photography.
"Frank would show up as a little dot that moves between two points," Richard "Doc" Kinne, an astronomical technologist at the American Association of Variable Star Observers in Cambridge, Mass., said in an interview. He helped write the citation that would lead to the naming.
While comets are often named for their discoverers, those who discover asteroids have 10 years to suggest a name once the discovery is verified.
A published citation officially naming the asteroid on July 3 notes Kameny's history as a gay rights pioneer.
"Frank E. Kameny (1925-2011) trained as a variable star astronomer in the 1950s, but joined the Civil Rights struggle. His contributions included removing homosexuality from being termed a mental disorder in 1973 and shepherding passage of the District of Columbia marriage equality law in 2009," the citation reads in the Minor Planet Circular.
Kinne said he and Billings wanted to honor Kameny for his legacy, even though he was pushed out of the astronomy field.
After Billings read Kameny's obituary, he wrote to Kinne.
"Hey, I have a few asteroids I discovered that I haven't named yet," he said. "What do you say we name one after Frank?"
"I was utterly floored," Kinne said. "To me, this is a big deal."
Billings told Kinne he was moved by hearing the story of how he had met Kameny about three years ago in Washington and many passers-by stopped to thank him for his advocacy.
"I concluded he was a man I would have admired," Billings wrote to Kinne. "Add that to the fact that I have many friends and acquaintances who are members of the LGBT community, and I felt it was something I wanted to do to honour Dr. Kameny—and my friends!"
Before Kameny died, Kinne and others had been working to present him with a certificate of recognition from the American Astronomical Society and perhaps create and fund an award in his honor. Kameny also received an official apology from President Barack Obama's administration for his firing years ago.
"He was an astronomer," Kinne said. "The culture of the time took that away from him, and now he's getting it back. He would have liked that."
Kinne and Billings submitted the citation for the asteroid late last year. By July, they hadn't heard whether it was approved and feared it had been rejected. On July 6, though, they got word that Kameny is an asteroid.
