'Rok' Solid Honour: Asteroids Named for Armagh Observatory Scientists

The International Astronomical Union has officially named two main-belt asteroids in honour of staff members at the Armagh Observatory and Planetarium in Northern Ireland. Slovenian-born space scientist Dr. Rok Nežič and meteorological officer Shane Kelly received the rare celestial recognition following citations approved by the global astronomy governing body. The designations highlight both astronomical research and decades of dedicated environmental data gathering.

Dr. Nežič, who serves as the institution's tours and outreach officer after completing his doctoral research in Armagh, had asteroid 20560 designated in his name. Orbiting in the vast asteroid belt between Mars and Jupiter, asteroid 20560 Nežič is estimated to measure more than 10 kilometres in diameter. Despite its substantial size, the celestial rock remains faint and requires high-powered astronomical telescopes to observe from Earth.

Welcoming the honour, Dr. Nežič remarked on the playful symmetry between his first name and having a massive celestial rock immortalized in deep space. His scientific career has explored cometary dust, planetary science, and polarimetry, while his outreach efforts have helped demystify the cosmos for thousands of visiting students and members of the public. He emphasized that sharing the wonders of astronomy remains at the core of his work.

The second distinction went to Shane Kelly, who had asteroid 7050 formally renamed Shanekelly in celebration of his decades of weather monitoring. As the observatory's meteorological officer, Kelly has maintained strict daily oversight of environmental instruments and weather logs. His persistent documentation continues a vital observational lineage that scientists rely upon to understand atmospheric trends.

The Armagh Observatory and Planetarium is uniquely positioned in the annals of global science, boasting one of the world's longest unbroken daily climate records. Founded in 1790, the Northern Irish institution has recorded meteorological conditions on a daily basis without interruption since 1795. This rich institutional history has made the facility a revered centre for both astronomical discovery and historical climate research.

Official asteroid naming follows a rigorous, multi-tiered process supervised by the International Astronomical Union's Working Group for Small Bodies Nomenclature. Once an asteroid's orbit is calculated with sufficient precision, discoverers are granted the privilege of proposing a formal name. The union reviews each submission against strict guidelines, reserving approvals for people who have made substantial contributions to science, culture, or exploration.

With these formal designations, Nežič and Kelly join an international roster of historic scientists, cultural figures, and pioneering researchers memorialized across the solar system. Observatory leadership celebrated the parallel honours as recognition of two complementary pillars of science: cutting-edge public engagement and painstaking, long-term observational monitoring. Both staff members reflect the enduring scientific mission sustained at the Armagh campus.

Armagh Planetarium plans to integrate the newly named minor planets into its educational displays, planetarium shows, and school workshops. Educators hope that highlighting asteroids named after active local staff will inspire young visitors to explore careers in STEM fields. Seeing living colleagues receive such timeless tributes demonstrates that space science is driven by accessible, community-grounded individuals.

Both asteroids will continue their silent, elliptical journeys around the Sun, taking several Earth years to complete each orbit through the main belt. For the Armagh Observatory community, the celestial bodies serve as a permanent testament to institutional dedication and international scientific teamwork. As research and outreach continue in Armagh, two rocks orbiting millions of miles away will carry their names for generations to come.
