Rutherfordium

Rutherfordium is a synthetic and highly radioactive element created exclusively through human-made nuclear reactions, making its occurrence virtually non-existent in natural astronomical settings. Due to its artificial production, rutherfordium is exceptionally rare beyond Earth, resulting in minimal astronomical significance. Its isotopes are characterized by extremely short half-lives, often lasting from milliseconds to minutes, further accentuating its absence in celestial bodies or cosmic environments. Rutherfordium's synthetic nature confines its existence primarily to controlled laboratory conditions, such as in nuclear reactors or as a byproduct of nuclear processes.
