Mercury.
The purpose of a satellite is that it observes the earth and it's movements. It also works the telephone, the Internet, radio's, navigation tools like GPS' and cell phones. if we didn't have satellites we wouldn't know anything about our planet and the solar systems so it's purpose is the observe the earth and discover things about it that can help with technology or even things with creation/religion etc.
A planet is an object that orbits a star, has enough gravity to make itself mostly round, and has cleared other objects out of its orbit. A satellite is an object that orbits another object that is itself orbiting a star. The object may be a planet, dwarf planet, asteroid, or comet.
The Moon is the only natural satellite of the Earth.
The Sun is the prime energy source for the planet earth. It burns and gives the planet light every day. The sun never goes out, but at certain times during the orbit of the satellite, the sun will affect how the satellite transmits. This is called a "sun outage" Sometimes, the sun will release large plasma masses called Coronal Mass Ejections, and these events may disrupt satellite TV. Satellite TV interference is common due to solar radiation, solar wind, and CMEs.
A lander is a space vehicle that is designed to land on other celestial body especially the Moon and the other planet.
The second satellite to be sent into Earth orbit was "Sputnik 2".
Mars.
Mercury
A satellite is anything that revolves around a larger mass or object. The Earth is a satellite of the Sun, while the moon is a satellite of the Earth. We have also launched a lot of machines into an orbit around the earth, which are also called satellites. They are used to study stars and the weather, for communication and to photograph our planet.
The Satellite Atlas orbits the planet Saturn.
An artificial satellite is a man-made object which is launched into space for the specific purpose of orbiting a planet or celestial body. Most are located in orbit around the Earth but there are many which perform research around other plants.
The most terrestrial planet in our Solar System is Mercury as evidenced by Mariner 10 satellite that flew by Mercury 3 times during 1974 and 1975. A new satellite, Messenger, was launched in 2004 and will be orbiting Mercury next year.
Oberon is a moon/satellite of the planet Uranus.
Planets are not launched.
A satellite.
A natural satellite that orbits a planet is a moon
