Above: Comet Lulin, coutesy of Giovanni Sostero and Ernesto Guido, Remanzacco Observatory.

Comet Lulin is getting ready to come nearly as close to Earth as Mars, at which point it's tail will look eight times as long as the full moon is wide. Analysis of it's orbit shows it is a real nomad, either from interstellar space, or from the Oort cloud of frozen solar system building blocks nearly a light year from the sun. Either way it should be pretty spectacular through a pair of binoculars or small telescope! Watch this space....
