Voyager I<\/a> was launched on September 5 in 1977. It is the farthest man-made object to Earth.<\/p>\n

\n

The Voyager 1<\/strong><\/em> spacecraft is a 733-kilogram robotic<\/a> space probe<\/a> of the outer solar system<\/a> and beyond, launched September 5<\/a>, 1977<\/a>, and is currently<\/a> operational. It visited Jupiter<\/a> and Saturn<\/a> and was the first probe to provide detailed images of the moons of these planets.<\/p>\n

Voyager 1<\/em> is the farthest man-made object from Earth<\/a>, traveling away from both the Earth and the Sun<\/a> at a relatively faster speed than any other probe. Though its sister-craft, Voyager 2<\/a><\/em>, was launched 1 month earlier, Voyager 2<\/em> will never pass Voyager 1.<\/em> Neither will the New Horizons<\/a><\/em> mission to Pluto<\/a>, despite being launched from Earth at a faster speed than both Voyager<\/em> craft. During its lifetime Voyager 1<\/em> has benefited from a number of gravity assisted<\/a> speed boosts.[1]<\/a><\/sup><\/p>\n

As of July 6<\/a>, 2007<\/a>, Voyager 1<\/em> is over 15.44 terameters<\/a> (15.44\u00d71012<\/sup> meters, or 15.44\u00d7109<\/sup> km, 103.2 AU<\/a>, or 9.6 billion<\/a> miles) from the Sun, and has thus entered the heliosheath<\/a>, the termination shock<\/a> region between the solar system and interstellar space<\/a>, a vast area where the Sun\u2019s influence gives way to the other bodies in the galaxy. If Voyager 1<\/em> is still functioning when it finally passes the heliopause<\/a>, scientists will get their first direct measurements of the conditions in the interstellar medium.<\/p>\n<\/blockquote>\n

Currently, light take 13.8 hours to reach Earth. How far is that?<\/p>\n

\n

As a basis for comparison, the Moon<\/a> is about 1.4 light seconds from Earth, the Sun<\/a> is about 8.5 light minutes away, and Pluto<\/a> is at an average distance of approximately 5.5 light hours. As of November 2005<\/a>, the spacecraft was traveling at a speed of 17.2 kilometers per second relative to the sun (3.6 AU per year<\/a> or 38,400 miles per hour<\/a>), 10% faster than Voyager 2<\/a><\/em>.<\/p>\n<\/blockquote>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"
