Moon
A small satellite named Dactyl orbits Ida. Dactyl, officially (243) Ida I Dactyl (/ˈdæktɨl/ DAK-til) was discovered in images taken by the Galileo spacecraft during its flyby in 1993. These images provided the first direct confirmation of an asteroid moon. At the time, it was separated from Ida by a distance of 90 kilometres (56 mi), moving in a prograde orbit. Dactyl is heavily cratered, like Ida, and consists of similar materials. Its origin is uncertain, but evidence from the flyby suggests that it originated as a fragment of the Koronis parent body.

Famous quotes containing the word moon:
“Shake off your heavy trance,
and leap into a dance,
Such as no mortals use to tread,
fit only for Apollo
To play to, for the Moon to lead,
And all the Stars to follow.”

“The quarrel of the sparrows in the eaves,
The full round moon and the star-laden sky,
And the loud song of the ever-singing leaves,
Had hid away earth’s old and weary cry.”
—William Butler Yeats (1865–1939)
“For now the moon with friendless light carouses
On hill and housetop, street and marketplace,
Men will plunge, mile after mile of men,
To crush this lucent madness of the face....”
