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:
“I thought to hear him speak
the girl might rise
and make the garden silver,
as the white moon breaks,
“Nossis,” he cried, “a flame.””
—Hilda Doolittle (1886–1961)
“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....”
—Allen Tate (1899–1979)
“The moon is door. It is a face in its own right,
White as a knuckle and terribly upset.
It drags the sea after it like a dark crime; it is quiet
With the O-gape of complete despair.”
—Sylvia Plath (1932–1963)
