Haley's comet is named after English astronomer Edmond Haley. A comet is a ghostly looking object in the night sky. Comets are made of frozen lumps of gas and rock. They are dirty snowballs. A comet becomes smaller each time it passes near the sun. As a comet approaches the sun it begans to heat up. Comets have no light of their own. Only when comets are near the sun they get bright and we can see them. Haley's comet is just one of two thousand known comets. Haley found that one bright comet had appeared in 1531. Haley 's comet appeared in 1986. Haley's comet comes by earth every 76 years. It will come again in 2062. We will be 64 years old. |
