current distance that the voyager 1 spacecraft is from earth
Voyager 1 Voyager 1 is a space probe launched by NASA on September 5, 1977. Part of the Voyager program to study the outer Solar System, Voyager 1 launched 16 days after its twin, Voyager 2. Having operated for 40 years, 7 months and 4 days as of April 9, 2018, the spacecraft still communicates with the Deep Space Network to receive routine commands and return data. At a distance of 141 AU (2.11×1010 km), approximately 21 billion kilometers (13 billion miles) from the Sun as of January 2, 2018,[3] it is the farthest spacecraft and man-made object from Earth.
Parallax To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term parallax is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit.[3] These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder.
