</ref> Juno ditemukan pada 1 September 1804 oleh seorang [[astronom]] asal [[Jerman]] bernama [[Karl Ludwig Harding|Karl L. Harding]] dan diberi nama mengikuti tokoh mitologi [[Yuno]], dewi Romawi yang paling tinggi.<ref>With two exceptions, 'Juno' is the international name, subject to local variation: Italian ''Giunone'', French ''Junon'', Russian ''Yunona''. The two exceptions are Greek, where the name was translated to its Hellenic equivalent, [[Hera]] (3 Ήρα), just as in the cases of [[1 Ceres]] and [[4 Vesta]], and Chinese, where it is called the 'marriage-god(dess) star' (婚神星 ''hūnshénxīng''). This contrasts with the goddess Juno, for which Chinese uses the Latin name (朱諾 ''zhūnuò'').</ref> Simbol planetari Juno yang masih sering terlihat adalah {{Unicode|⚵}} ([[Berkas:Juno symbol.svg|30x20px|Old symbol of Juno]]), walaupun kemudian diganti dengan ③.
