The most famous of all comets visits the inner Solar
System once every seventy-six years. At present, it is on the outward leg of its journey, beyond the orbit
of Uranus, but it can be expected to return to the skies of Earth
in November 2061.
Halley's Comet is presently travelling through the constellation of Hydra, passing beneath the 'head' of the Sea Monster. This chart shows its position at five-year intervals until 2015.
