These 4 asteroids just got named for Pope Leo XIII, Vatican astronomers
Four asteroids have been named after Pope Leo XIII by Vatican astronomers at the Vatican Observatory. The naming honors the pope’s role in re‑establishing the observatory in 1891. The announcement was made on April 29, 2026, following a recent visit by Pope Leo XIV to the observatory. The act continues a tradition of naming celestial bodies after popes, complementing other papal honors such as shrines and schools.

The Vatican Observatory announced that four newly discovered asteroids have been officially named, honoring Pope Leo XIII and three historic figures associated with the Observatory. The names were approved by the International Astronomical Union’s Working Group on Small Bodies Nomenclature and reflect the Vatican’s long‑standing commitment to scientific research.
The asteroids were detected by Lithuanian astronomer Kazimieras Cernis and Jesuit astronomer Father Richard P. Boyle using the Vatican Advanced Technology Telescope (VATT) on Mount Graham, Arizona 1 2. Their names were unveiled in the IAU’s Working Group on Small Bodies Nomenclature (WGSBN) Bulletin dated April 13, 2026.
These designations follow the IAU protocol: a provisional designation is assigned at discovery, a permanent number is granted once the orbit is well determined, and discoverers may then propose a name for IAU approval 1 2.
Pope Leo XIII re‑established the Vatican Observatory in 1891 through the motu proprio Ut Mysticam, emphasizing the Church’s support for “a most noble science” that lifts humanity toward contemplation of heavenly events 1 2. The Observatory traces its origins to Pope Gregory XIII’s 1582 calendar reform and operated intermittently from 1789 to 1821 before its modern revival.
Increasing light pollution in Rome prompted the relocation of the Observatory’s telescopes to the Apostolic Palace at Castel Gandolfo and later to the VATT in Arizona during the 1990s 1 2. The current director, Jesuit Father Richard D’Souza, was appointed by Pope Leo XIV in July 2025 1.
The naming of these asteroids underscores the Vatican’s ongoing effort to demonstrate the harmony between faith and science. Pope Leo XIII joins Pope Gregory XIII (asteroid (560974) Ugoboncompagni) and Pope Benedict XVI (asteroid (8661) Ratzinger) as popes commemorated in space 1. The Observatory also notes other Vatican‑related minor planets, such as (90718) Castel Gandolfo.
Catholic observatories honor popes through celestial naming
I can analyze this, but I don’t yet have the actual <news_summary> content to base the analysis on. Your message only states a headline idea (“Catholic observatories honor popes through celestial naming”) without the accompanying details (which pope, which celestial bodies, which observatory actions, dates, and what exactly was reported).
Please paste the full <news_summary> text (or a link’s text if that’s all you have). Then I will provide an in-depth analysis using only the Catholic sources provided to me in <references> and explain how (or whether) the reported practice aligns with Catholic teaching and Church context.
