3 Juno (symbol: .svg){kind=small}
) is a main belt asteroid discovered by Karl Ludwig Harding on September 1, 1804.[1] Juno was the third asteroid discovered in the Solar System and is named after Juno, the Roman goddess that is the queen of all gods.[2]
Juno is an S-type asteroid,[3] and is estimated to contain 1% of the total mass of the asteroid belt.[4]
Juno orbits at a slightly closer distance to the Sun than Ceres or Pallas. Its orbit is inclined at around 12° to the ecliptic, but has very big eccentricity in its orbit. [5]
Juno is in the Juno clump, a group of asteroids that share similar orbits, the biggest asteroid of the Juno clump is (32326) 2000 QO62 being 6 kilometers. [6]

A variant of the astronomical symbol for 3 Juno.[1] There are several such variants, some tilted at a diagonal to give more room for orbs etc. on the scepter. Adopted for asteroid (103) Hera, the Roman equivalent of Juno. (Martha Lang-Wescott places the cross between the orb and the star for 103 Hera.)
