Juno is the largest member of the Juno family of asteroids.
Juno was the first asteroid for which an occultation was observed. It passed over a dim star on February 19, 1958. Since then, several occultations by Juno have been observed.
Juno was recently imaged by the Hooker telescope at Mount Wilson Observatory, using adaptive optics. The study revealed that Juno has had a 100-kilometre crater blasted out of it by an ancient impact, which makes the asteroid look as though a 'bite' has been taken out of it.
