Reading: Read the text about Satellites and answer the questions.
A satellite is a small object that orbits around a larger object in space. Satellites can be natural or artificial (made by people). All the planets in the solar system except Mercury and Venus have natural satellites. Earth’s moon is one example. Artificial satellites are sent into space to gather information. Most are launched into space by rockets. The first successful U.S. satellite was Explorer 1. It was launched in 1958. Now dozens of new satellites are put into space every year. Artificial satellites have many purposes. Scientific satellites collect information about space. Communications satellites help send telephone calls, radio and television programs, and computer information all over the world. A space station is a special kind of satellite used by astronauts. Astronauts live on a space station for months so as they can gather information and do experiments.
