Four amateur astronomers working on NASA’s citizen science project, The Daily Minor Planet, were honored for their contributions to astronomy and planetary science by having asteroids in the asteroid belt between Mars and Jupiter named after them. These volunteers reviewed enormous amounts of image data in search of new asteroids and served as moderators in the online “Talk” bulletin boards for the project. These newly named asteroids, (91333) Robertogorelli, (91335) Alexandrov, (91212) Virgiliogonano, and (91389) Davidsaewert were approved by the International Astronomical Union (IAU) this summer.

“It was a dream since I was young, and now, it has become reality—a magnificent reality,” said Virgilio Gonano, a volunteer from Italy whose name is now on an asteroid. “I still have to get used to it and maybe I never will. I must also say thanks to my Citizen Scientist friends on Zooniverse—wonderful people who I have come to know and appreciate and who share with me the passion for astronomy and amateur research.“

“The news that an asteroid had been named after me came as a complete surprise to me,” said Roberto Gorelli, another amateur who was honored. “I dedicated this event to my parents, who worked hard to educate me and my brothers.” Roberto has participated in many other NASA citizen science projects besides The Daily Minor Planet. His favorites include Stardust@Home and Planet Hunters TESS.

Each newly named asteroid comes with a short dedication and biography of its namesake. These are listed here:.
