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:
“In his time, this one had little to speak of,
The softest word went gurrituck in his skull.
For him the moon was always in Scandinavia
And his daughter was a foreign thing.”
—Wallace Stevens (1879–1955)
“When the moon hits your eye like a big pizza pie, that’s amore.”
—Jack Brooks (1912–1971)
“So, we’ll go no more a-roving
So late into the night,
Though the heart be still as loving,
And the moon be still as bright.
For the sword outwears its sheath,
And the soul wears out the breast.
And the heart must pause to breathe
And love itself have rest.”
—George Gordon Noel Byron (1788–1824)
