voyager 2









































voyager 2 is a space probe launched by nasa on august 20, 1977, to study the outer planets. part of the voyager program, it was launched 16 days before its twin, "voyager 1", on a trajectory that took longer to reach jupiter and saturn but enabled further encounters with uranus and neptune. it is the only spacecraft to have visited either of these two ice giant planets.

on september 9, 2012, "voyager 2" was from the earth and from the sun; and traveling at (relative to the sun) and traveling outward at about 3.256 au per year. sunlight takes 13.73 hours to get to "voyager 2". the brightness of the sun from the spacecraft is magnitude -16.7. "voyager 2" is heading in the direction of the constellation telescopium. (to compare, proxima centauri, the closest star to the sun, is about 4.2 light-years (or ) distant. "voyager 2's" current relative velocity to the sun is . this calculates as 3.254 au per year, about 10% slower than "voyager 1". at this velocity, 81,438 years would pass before "voyager 2" reaches the nearest star, proxima centauri, were the spacecraft traveling in the direction of that star. ("voyager 2" will need about 19,390 years at its current velocity to travel a complete light year)
