What Does the Name Astro Mean?
Astro means "star." It comes from the Greek word astron (ἄστρον), "star," which was borrowed into Latin as astrum and survives in Spanish, Portuguese, and Italian as astro, where it names a star or any other heavenly body. Greek astron is related to astēr (ἀστήρ), also "star," and the same root produced the English combining form astro-, as in astronomy and astronaut. This is a literal meaning, not a symbolic one: the name is the plain word for a star, with no separate traditional etymology of its own.
Astro Name History & Origins
The word behind the name is ancient, but its use as a personal name is modern and limited. In classical Latin poetry, the plural astra commonly means "the stars" or "the constellations," and the singular astrum is a star or heavenly body. From Latin the word passed into the Romance languages as astro, where it remained an ordinary noun rather than a common given name.
In English, the element astro- entered scientific vocabulary through Latin and Greek, appearing in words such as astronomy, and later in nineteenth- and twentieth-century coinages like astrophysics and astronaut. That background made "astro" a familiar word even though it was not an established English personal name.
Well-known uses belong to popular culture rather than to the name's origin. The robot hero of Osamu Tezuka's manga Tetsuwan Atom (1952) was renamed Astro Boy for the English-language television adaptation in the 1960s, and the family dog in the animated series The Jetsons (1962) is named Astro. The word has also been adopted as a group name by the South Korean band Astro, which began performing in 2016. These are notable associations of the word, not evidence about when it was first used as a person's name.
