Slide1 : Other Solar System Bodies
Comets
Slide2 : Halley’s Comet Sir Edmond Halley (1656-1742) proposed that the comet seen in 1682 was periodic in nature and identified it as being the same as those seen since 1305. He predicted its return in 1758, and the comet was named for him in spite of his death prior to its actual return. Comets have long struck awe in observers and the passage of Halley’s Comet in 1066 was recorded in the Bayeaux Tapestry.
