York’s solar system model


Voyager 1


The two space probes Voyager 1 and Voyager 2, were launched in 1977. In August 2012 Voyager 1 became the first man-made object to enter inter-stellar space. Voyager 2 was launched first to allow it to fly by Jupiter, Saturn, Uranus and Neptune.  Voyager 1 was able to fly by only Jupiter and Saturn, where it came close to Saturn’s largest moon, Titan. 

Voyager 1 weighs 773 kilograms and the main body of the space craft is about the size of a small car.  The longest boom is 13 metres long.

This model of the Voyager 1 space probe is one third the size of the real thing and was built by Dave Coulthard, one of the scientists responsible for the solar system model.
