Reading SkillsA REGULAR VISITOR
In 1682, a bright comet appeared in the night sky. An astronomer named Edmond G. Halley noticed that the comet matched the descriptions given of previous comets seen in 1531 and 1607. Halley theorized that this was the very same comet, in a 76-year orbit around the sun, and he predicted that the comet would return in 1758. Due to the gravitational pull of Jupiter and Saturn, the comet was a bit later than predicted, but it arrived in March 1759.

Since then, the comet has returned in 1835, 1910, and 1986. Halley’s comet is not expected to visit Earth again until 2061, but comet fans can see bits and pieces of the comet each year during the annual Orionids meteor shower. This meteor shower occurs when Earth crosses the comet’s orbital path, which is made of tiny debris particles of rock and ice, usually no bigger than grains of sand. Although they are very small, these tiny meteors make brilliant shooting stars when they strike Earth’s atmosphere, because they travel at nearly 145,000 km/h.

14. Why are tides weakest when Earth, the sun, and the moon are not aligned?
Answer: When the Earth, sun and moon are at right angles as shown in the diagram, the directions in which ocean water is pulled don’t add up to high tides anywhere on Earth.
