Biography

He is the son of Jacek Wierzchoś, chemist, and former employee of the Polish Academy of Sciences, and Janina Wierzchoś, dentist.[2] In the early 1990s, his family immigrated to Spain, where he graduated in physics from the Complutense University of Madrid.[3] In 2019, he defended his doctorate, concerning comets,[4] at the University of South Florida. He currently works at the Mount Lemmon Survey observatory as part of the Catalina Sky Survey project.[3]

In this context, he discovered several asteroids. In particular, along with Theodore Pruyne he co-discovered 2020 CD3 on 15 February 2020,[1] then a temporary satellite of Earth.[5][6] In April of the same year, he discovered a long-period comet, which consequently bears his name: C/2020 H3 (Wierzchoś).[3] In September 2021, he discovered his second comet, periodic comet: P/2021 R4 (Wierzchoś).[7][4] Other comets discovered by him include: P/2021 U1 (Wierzchos), P/2022 B1 (Wierzchos), C/2024 E1 (Wierzchos) and C/2024 G1 (Wierzchos).

He is married and lives with his wife in Tucson, Arizona.[8] He speaks Polish, Spanish, English and Catalan.[8]
