A white arrow marks Pluto in this New Horizons Long Range Reconnaissance
Imager (LORRI) picture taken Sept. 21, 2006. Seen at a distance of about
4.2 billion kilometers (2.6 billion miles) from the spacecraft, Pluto is
little more than a faint point of light among a dense field of stars. Mission
scientists knew they had Pluto in their sights when LORRI detected an
unresolved "point" in Pluto's predicted position, moving at the planet's
expected motion across the constellation of Sagittarius near the plane of
the Milky Way galaxy.
Photojournal Note: There is debate within the science community as to whether Pluto should be classified as a Planet or a dwarf planet.
