Voyager 1

At 22:13 UTC (or 08:21:32 UTC without light-time correction), Voyager 1 was at a distance of 100 AU (approximately 14.96 terameters, 9.3 billion miles or 0.002 light years) from the Sun, which makes it the most distant artificial object from Earth. At this distance, it is more distant from the Sun than any known natural solar-system object, including 90377 Sedna. Though Sedna has an orbit that takes it 975 AU away from the Sun at apihelion, as of 2006 it is less than 90 AU away from the Sun and approaching its perihelion at 76 AU.

At its current distance, light (which travels 186,282.397 miles per second (299,728.376773 kilometers per second) takes over 13.8 hours to reach the spacecraft from Earth. As a basis for comparison, the Moon is about 1.4 light seconds from Earth, the Sun is about 8.5 light minutes away, and Pluto is at an average distance of approximately 5.5 light hours. As of November 2005, the spacecraft was travelling at a speed of 17.2 kilometers per second relative to the sun (3.6 AU per year or 38,400 miles per hour), 10% faster than Voyager 2. Accurate information concerning its location can be found in this NASA paper with heliocentric coordinates extrapolated up to 2015 of both probes. It is not heading towards any particular star, but in 40,000 years it will be within 1.7 light years of the star AC+793888 in the Camelopardis constellation.

Voyager 1, as of September 2006, is at 12.22° declination and 17.051hrs Right Ascension, placing it in the constellation Ophiuchus. NASA continues daily tracking of the spacecraft with the Deep Space Network stations.

What I find so amazing, is that last statement in the second-to-last paragraph...
...but in 40,000 years it will be within 1.7 light years of the star AC+793888 in the Camelopardis constellation.

This is a listing of stars that we can see.... Let alone the ones that are beyond our feeble 'Hubble-assisted' sight. And notice how far away from the sun it is right now: 0.002 light years, after 30 years of traveling at 38,400MPH. And we think that we are big stuff—able to live without God, because of the might of our nation. If this does not show people that we are but dust, I'm not sure what will!
