June 13th - Pioneer 10

Updated: Feb 13, 2023

Today is the anniversary of the first time a man-made object left our solar system: Pioneer 10, a space probe launched in 1972. Today in 1983, 11 years after the launch, the humble space probe crossed Neptune's orbit, leaving the solar system it was created in.


In 2002, nearly two decades after it left the only solar system anyone reading this will likely ever know, Pioneer 10 went offline. Its last signal was received by scientists on Earth in 2003. Pioneer 10 is now believed to be on a 2 million year pilgrimage to the second nearest star to it, a reddish-orange giant star named Aldebaran by some humans.
