Flashback to Neptune's Moon Triton
Jet Propulsion Laboratory
August 25, 2009
Newly released images commemorate the 20-year anniversary of the
Voyager
flyby of Neptune's moon Triton on Aug. 24, 2009.
Triton was the last solid object visited by NASA's Voyager 2
spacecraft
as it headed toward the edges of our solar system.
Triton, Neptune's largest moon, is one of the "coolest" objects in the
solar system, literally, with a surface temperature of minus 235
degrees
Celsius (minus 391 degrees Fahrenheit). Voyager 2 discovered that
Triton
has active geysers.
The images and a movie show the moon's sparsely cratered surface with
smooth volcanic plains, mounds and round pits formed by icy lava
flows.
The Voyagers are the farthest human-made objects in the solar system.
Voyager 1 is 16.6 billion kilometers (10.3 billion miles) or about 111
Astronomical Units from the Sun. Voyager 2 is 13.5 billion kilometers
(8.4 billion miles) or about 90 Astronomical Units from the Sun. Both
are expected to reach interstellar space in five to eight years (2014
-
2017).
