u'''<b>Do you know Triton, one of the namesakes for our project?</b>

Triton (pronounced /ˈtraɪtən/ TRYE-tən, or as in Greek Τρίτων) is the
largest moon of the planet Neptune, discovered on October 10, 1846
by William Lassell. It is the only large moon in the Solar System
with a retrograde orbit, which is an orbit in the opposite direction
to its planet's rotation. At 2,700 km in diameter, it is the seventh-largest
moon in the Solar System. Triton comprises more than 99.5 percent of all
the mass known to orbit Neptune, including the planet's rings and twelve
other known moons. It is also more massive than all the Solar System's
159 known smaller moons combined.
