Moon
In 2005, the adaptive optics team at the Keck telescopes in Hawaii carried out observations of the four brightest TNOs (Pluto, Makemake, Haumea, and Eris), using the newly commissioned laser guide star adaptive optics system. Images taken on September 10 revealed a moon in orbit around Eris. In keeping with the "Xena" nickname already in use for Eris, Brown's team nicknamed the moon "Gabrielle", after the television warrior princess's sidekick. When Eris received its official name from the IAU, the moon received the name Dysnomia, after the Greek goddess of lawlessness who was Eris's daughter. Brown says he picked it for similarity to his wife's name, Diane. The name also retains an oblique reference to Eris's old informal name Xena, portrayed on TV by Lucy Lawless.

Famous quotes containing the word moon:
“Whenever the moon and stars are set,
Whenever the wind is high,
All night long in the dark and wet,
A man goes riding by.”
—Robert Louis Stevenson (1850–1894)
“In such a night, when passing clouds give place,
Or thinly veil the heaven’s mysterious face;
When in some river, overhung with green,
The waving moon and trembling leaves are seen;”
—Anne Finch, Countess Of Winchilsea (1661–1720)
“the broad cloud-driving moon in the clear sky
Lifts o’er the firs her shining shield,
And in her tranquil light
Sleep falls on forest and field.
See! sleep hath fallen: the trees are asleep:
The night is come. The land is wrapt in sleep.”
—Robert Bridges (1844–1930)
