The IAU names an asteroid after Lithuanian astronomer Kazimieras Černis, recognizing his decades of celestial discoveries and religious dedication.
Newsroom (16/04/2026 Gaudium Press ) In a tribute that bridges science, faith, and history, Lithuanian astronomer Kazimieras Černis—known for naming dozens of celestial bodies after Jesuits and other figures of the Church—has himself been immortalized among the stars. A newly christened asteroid, now officially titled (29692) Černis, orbits in the vast belt between Mars and Jupiter, bearing the astronomer’s name as published in the latest bulletin (No. 6/2026) of the International Astronomical Union’s Working Group on the Naming of Minor Celestial Bodies.
This honor recognizes Černis’s lifelong contributions to the study of the cosmos. Born in 1958, Černis is a senior researcher at Vilnius University’s Institute for Theoretical Physics and Astronomy, where his work has focused on stellar photometry, interstellar dust clouds, and the behavior of small celestial bodies that populate our solar system. Over his career, he has contributed to the discovery of numerous comets and hundreds of asteroids, earning him a respected place in the global astronomical community.
The naming initiative was proposed by Venezuelan astronomer Orlando A. Naranjo, who teaches astrophysics at the Universidad de Los Andes in Mérida, originally founded as a seminary in 1785—a gesture that underscores the enduring interplay between scientific curiosity and religious heritage.
Honoring Those Who Bridged Science and Theology
Černis’s newly named asteroid joins a cluster of celestial bodies dedicated to others who shaped the dialogue between faith and science. Among them are the Belgian Jesuit Florent Constant Bertiau (1919–1995)—honored as (688696) Bertiau—the Italian Oratorian priest Giuseppe Lais (1845–1921)—now (836955) Lais—and Lithuanian philosopher Saulius Kanišauskas (born 1945)—whose namesake asteroid is (262284) Kanišauskas.
In each case, Černis’s involvement went beyond admiration; he directly mapped these asteroids, granting him the right to propose names to the IAU. The tradition of celestial naming thus continues to merge scientific achievement with cultural and spiritual recognition.
Bertiau was a pioneer at the Vatican Observatory, where he founded its data center in 1965 and advanced computer-assisted data analysis—well before such tools became a staple of modern astronomy. His studies into light pollution and the distribution of stars in the Milky Way were ahead of their time.
Meanwhile, Lais, a devoted Oratorian priest, was instrumental in establishing the Vatican Observatory itself. For thirty years, he served as its deputy director, playing a central role in the monumental Carte du Ciel project, an early international effort to map the stars with unprecedented precision.
Philosopher Kanišauskas, the director of the Vilnius Planetarium, made his mark as a bridge-builder between science and religion. His publications have explored the philosophical and ethical dimensions of astronomy, making his recognition as a minor planet namesake a symbolic continuation of that dialogue between reason and faith.
Church Figures in the Sky
The Jesuits remain particularly prominent in the cosmic lexicon. To date, roughly fifty members of the order have been honored with asteroid names, thanks to their historic commitments to education, exploration, and astronomical research. Yet the church’s representation among minor planets extends beyond scientific contributions. Earlier this year, the IAU recognized figures such as Saint Faustina and Polish nun Ursula Ledóchowska, highlighting a growing appreciation for spiritual and cultural heritage alongside empirical achievement.
How Asteroids Earn Their Names
Behind every cosmic christening lies a meticulous process governed by the IAU’s Minor Planet Centre. A newly detected celestial body must first be observed on two consecutive nights for verification. These sightings are then cross-referenced with previous, unidentified bodies, merging duplicates and defining precise orbital paths. Once the orbit is confirmed, the asteroid receives a permanent number.
Only then does naming begin. The right belongs not to the first observer but to the researcher who gathers sufficient data to calculate its orbit—an acknowledgment of the labor that transforms fleeting light into mapped motion. Proposed names undergo review by the Minor Planets Naming Working Group, ensuring that each designation adheres to tradition, clarity, and respect for the scientific record before becoming official.
A Legacy Written in the Heavens
For Černis, the recognition is not merely personal—it reflects a broader story of how science and faith, far from opposing forces, continue to illuminate one another across centuries. Through his tireless observation and thoughtful naming, he has woven a bridge between the empirical and the eternal. Now, as (29692) Černis circles silently through the asteroid belt, his name joins those he once honored—forever inscribed among the stars he so carefully studied.
