Vatican Astronomer Becomes 11th Jesuit to Have an Asteroid Named for Him

June 25, 2020 — One more Jesuit has had an asteroid named for him.

Fr. Chris Corbally, SJ, a stellar astronomer at the Vatican Observatory in Arizona, has had his name attached to a rocky body in the asteroid belt that orbits the sun in slightly less than four years.

The honor was a surprise, Fr. Corbally said.

“I’m not a kind of an asteroid guy” like some of his colleagues at the observatory, he said. “For me it came a as complete surprise. That’s why it’s kind of nice.”

The particular asteroid, designated 119248 Corbally, is about a mile across in size. It was discovered Sept. 10, 2001, by Roy Tucker, a recently retired senior engineer from the Imaging Technology Laboratory at the University of Arizona.

Tucker has worked extensively with Vatican astronomers. His work included building and maintaining the charge-coupled device cameras used for digital imaging of celestial objects at the Vatican Advanced Technology Laboratory as well as on telescopes used by Fr. Corbally at the University of Arizona’s Steward Observatory.

Naming an asteroid requires approval from a committee of the International Astronomical Union. Once named, a short citation about the person being honored is published in a circular from the IAU’s Minor Planet Center.

Asteroids are small rocky bodies that orbit the sun. Thousands of them are located in the asteroid belt between the orbits of Mars and Jupiter. But some have orbits that bring them into other locations in the solar system.

Born in London, Fr. Corbally, 74, has been on the Vatican Observatory staff since 1983. He joined the observatory after completing a doctorate degree in astronomy from the University of Toronto. He was vice director of the Vatican Observatory Research Group until 2012.

Fr. Corbally has a wide range of research interests. They have spanned multiple star systems, stellar spectral classification, activity in solar-type stars, galactic structure and star formation regions and telescope technology.

“I’m very much a star man. But realizing that stars are in our galaxy, I’m also interested in galactic structure and history of star populations in our galaxy. My way of probing all this is through the individual stars,” he told Catholic News Service.

The Jesuit’s current research focuses on the characteristics of human sentience in the context of evolution.

Research by the Vatican Observatory has turned up at least 10 asteroids named for Jesuits, including St. Ignatius of Loyola, founder of the Society of Jesus.

Other asteroids have been named for Corbally’s contemporaries: Br. Guy Consolmagno, SJ, director of the Vatican Observatory and president of its foundation; Fr. Richard Boyle, SJ, and Fr. Jean Baptiste Kikwaya, SJ, astronomers at the observatory; and Br. Robert Macke, SJ, a research scientist and meteorite curator for the observatory.

In addition, asteroids have been named for Fr. George Coyne, SJ, a onetime observatory director of who died Feb. 11; Fr. Christopher Clavius, SJ, whose mathematical measurements helped develop the Gregorian calendar; Fr. Roggiero Boscovich, SJ, an 18th-century mathematician; Fr. Maximilian Hell, SJ, who determined the solar parallax from observations of Venus as it transited in front of the sun in 1769; and Fr. Angelo Secchi, SJ, director of the Roman College observatory in Rome during the 19th century. [Source: CNS]
