These are the dragons of the night sky, from stars to meteor showers.
Draco
Draco, 'the dragon', is a constellation visible in the northern hemisphere.
Draconid Meteors
This meteor shower is also know as the Giacobinid meteors. These meteors
are associated with the Giacobini-Zinner comet (Comet 21P). The meteor showers
happens yearly in early October, though are usually not very spectacular. There
have been a few exceptional years, such as the spectacular showers in 1933
and 1946. The last close pass to Earth by the Giacobini-Zinner comet was in
1998. The next is expected in 2018.
Giacobini-Zinner is noteworthy as the first comet to be visited by a
spacecraft. In 1985 ICE (International Cometary Explorer) passed close to
the comet, passing through its tail. It is named after its discoverers...
Michel Giacobini who discovered it in 1900, and Ernst Zinner who rediscovered
it in 1913.
