Imagine a celestial tribute to the guardians of our planet—a cosmic honor roll etched into the stars. In 2025, the International Astronomical Union (IAU) bestowed a unique honor upon the European Space Agency (ESA) by naming 10 asteroids after individuals and locations pivotal to its Planetary Defence program. But here's where it gets fascinating: these aren't just any asteroids; they're symbols of humanity's effort to safeguard Earth from potential cosmic threats. Let's dive into this stellar recognition and explore the stories behind these newly christened space rocks.
Asteroid ESOC: A Giant Named After a Giant in Space Operations
The asteroid formerly known as 2021 FE40 now bears the name (810657) ESOC, honoring ESA’s European Space Operations Centre in Darmstadt, Germany. For nearly six decades, ESOC has been the nerve center for Europe’s most ambitious space missions, from Earth-orbiting satellites to far-flung explorers of planets, comets, and asteroids. Interestingly, ESOC also houses the administrative hub for ESA’s Space Safety Programme, including the Planetary Defence team. Discovered in March 2021 by astronomer Erwin Schwab and ESA’s former Head of Planetary Defence, Detlef Koschny, this asteroid is estimated to be between 600 and 1,300 meters wide—at least twice the size of its terrestrial namesake. It orbits the Sun beyond Mars, a silent sentinel in the vastness of space.
A Celestial Celebration and a Bold Statement
Schwab and Koschny were invited to ESOC to commemorate this naming during ESA Director of Operations Rolf Densing’s New Year’s address on January 13. Densing aptly remarked, ‘The naming of these asteroids after ESA sites, astronomers, mathematicians, mission analysts, and others celebrates the extraordinary work of the Planetary Defence Office and all teams dedicated to studying asteroids and protecting our planet.’ But here’s where it gets controversial: as we name more celestial bodies after human achievements, are we truly honoring science, or are we projecting our ego onto the cosmos?

The Full Roster of Cosmic Honorees
(810657) ESOC is just one of 10 asteroids—and one comet—named in 2025 to honor ESA’s Planetary Defence heroes. Here’s the full list, each with a story as compelling as the next:
- (126247) Laurafaggioli: Named after Laura Faggioli for her work on asteroid orbit determination and risk assessment.
- (126248) Dariooliviero: Honoring Dario Oliviero for providing critical operational data to the Planetary Defence team.
- (296587) Ocaña: Celebrating Francisco Ocaña’s career-long contributions to Planetary Defence, particularly within ESA.
- (457818) Ramírezmoreta: Recognizing Pablo Ramírez Moreta’s research in astronomy and his role in ESA’s Planetary Defence efforts.
- (826631) Frascati: Named after the Italian city home to ESA’s European Space Research Institute (ESRIN), which hosts the Near-Earth Object Coordination Centre (NEOCC).
- (438881) Michaelkhan: Honoring Michael Khan for his contributions to missions like Hera and Ramses.
- (386618) Accomazzo: Celebrating Andrea Accomazzo’s leadership in missions to small Solar System bodies, including Rosetta and Hera.
- (321480) Juanluiscano: Recognizing Juan Luis Cano’s engineering and project management, including his role in the ‘Don Quijote’ concept that evolved into the international Asteroid Impact & Deflection Assessment collaboration.
- (241373) Richardmoissl: Named after Richard Moissl, current Head of ESA’s Planetary Defence Office, for his contributions to the Office and ESA missions.
- Comet P/2025 W3 (Kresken): Named after its discoverer, ESA astronomer Rainer Kresken.
How Do Asteroids Get Their Names? A Peek Behind the Curtain
The naming process is meticulously managed by the IAU’s Working Group for Small Body Nomenclature. When an asteroid is discovered, it receives a provisional designation based on the date of discovery. For instance, in ‘2021 FE40,’ ‘2021’ is the year, ‘F’ denotes the second half of March, and ‘E40’ indicates it was the 1005th asteroid discovered in that period. Once its orbit is confirmed, it gets a permanent number—(810657) ESOC was the 810,657th asteroid to receive one. Discoverers then propose a name, which must be 16 characters or fewer, pronounceable, and non-offensive. And this is the part most people miss: certain asteroid families follow naming traditions, like Jupiter’s Trojans named after figures from the Trojan War.
Final Thoughts: A Cosmic Legacy or a Humbling Reminder?
As we name asteroids after our heroes, we’re reminded of both our achievements and our vulnerability. These celestial bodies aren’t just rocks—they’re symbols of our collective effort to understand and protect our world. But as we inscribe our names on the cosmos, are we truly masters of the universe, or are we merely guests in a vast, indifferent void? Share your thoughts below—let’s spark a conversation as boundless as the stars themselves.
