Miranda, Chevron, and Alonso
Explanation:
Miranda is a bizarre world which surely had
a
tempestuous past.
The innermost of the larger
Uranian moons, Miranda is almost 300 miles
in diameter and was
discovered on today's
date in 1948 by
American planetary astronomer
Gerard Kuiper.
Examined very closely by
the Voyager 2 spacecraft in 1986, this
dark and distant
world turned out to be quite a
surprise.
Miranda was found
to display a unique, bewildering
variety
of terrain
leading some to suggest that it has been
fractured up to 5 times during its evolution.
Along with the famous "chevron" feature, the bright V-shaped area just
above center,
this composite of the highest resolution images of
Miranda
shows wild
juxtapositions of ridges and valleys, older cratered and younger smooth
surfaces, and shadowy canyons perhaps 12 miles deep.
The large crater (below center) is the 15 mile wide crater
Alonso.
