Halley's comet is probably the world's most famous - certainly its most well known - comet! It returns to the vicinity of the Earth every 75 years and was last here in 1986. We can next look forward to a visit in about 2061.
Did you know that Halley's Comet was seen in 1066 - a very important year for England? Afterwards people decided that it was a sign of the invasion to come from Normandy and the death of their king, Harold at the Battle of Hastings.
