3 Juno (jew'-noe (key)) was the third asteroid to be discovered and is one of the largest main belt asteroids, being the heaviest of the stony S-type. It was discovered on September 1, 1804 by German astronomer Karl L.

JUNO
Juno is a large asteroid, and one of the four brightest asteroids. It is about 240 km in diameter and its mass is roughly 2.0 x 1019 kg. It is about 2.7 AU from the Sun and takes 4.36 years to orbit the Sun once (its year).

Juno will orbit closer to Jupiter than any previous spacecraft. It will use Jupiter's magnetic field, gravity field and naturally occurring radio waves to study the mysterious interior of the giant planet.

Callisto was a beautiful maiden who enticed Jupiter, thereby invoking the wrath of Juno, Jupiter's wife. She turned Callisto into a bear. After Io's romance with Jupiter, she was turned into a heifer, pursued by Juno's gadfly (I'm not making this up! ...
El estatus de Ceres como el cuarto planeta fue puesto en duda sólo unos cuantos años más tarde, cuando Vesta y Juno (asteroides más pequeños) se encontraron en orbitas similares.
It is interesting to note that, historically, the first four asteroids (1 Ceres, 2 Pallas, 3 Juno and 4 Vesta) were considered planets for several decades (their size was not accurately known at the time).
The legends say that the goddess of the heavens, Juno (the Greek Hera) ordered a hundred-eyed giant, Argos Panoptes, to keep his eyes on her errant husband, Jupiter. He ordered Argos slain and Juno transformed the 100 eyes into the Peacock's tail.
Mars was the son Jupiter (Zeus) and Juno (Hera). Both of them supposedly hated their son. His sister is Eris (Discord), and his nephew is Strife. He walks with Bellona (Enyo), the goddess of war. She brings with her Terror, Trembling, and Panic.
Soon other small bodies were discovered in that region (Pallas in 1802, Juno in 1804 and Vesta in 1807), so the Celestial Police concluded that not just one, but many minor planets had to exist in a main asteroid belt.
Three other asteroids (2 Pallas, 3 Juno, and 4 Vesta) were discovered over the next few years, with Vesta found in 1807. After eight more years of fruitless searches, most astronomers assumed that there were no more and abandoned any further searches.

Instead of a planet, they discovered a series of small, faint bodies: Ceres in 1801, Pallas in 1802, Juno in 1804 and Vesta in 1807.
Piazzi named it Ceres, after the Sicilian goddess of grain. Three other small bodies were discovered in the next few years (Pallas, Vesta, and Juno). By the end of the 19th century there were several hundred.
He detected Ceres in 1801 and measured its orbital semi-major axis to be 2.8 A.U."exactly where the "law" predicted. Within a few years, three more asteroids"Pallas (at 2.8 A.U.), Juno (at 2.7 A.U.), and Vesta (at 3.4 A.U.)"were discovered.
