I only know 2 which are the Hubble telescope and the curiosity rover.
Three well-known man-made satellites are the International Space Station (ISS), the Hubble Space Telescope, and the Global Positioning System (GPS) satellites.
Satellites can be natural, and satellites can be man-made. They cannot be both. Satellites are either natural or man-made.
by satellites we can know about the things happening on earth at a time.
Satellites are man made objects, they can not "evolve".
The definition of a "satellite" is anything that orbits a larger body. Moons are satellites (natural satellites), and Neptune has 13 known moons.
man made satellites are used to orbit around the earth. these satellites collect information that can be used for communication, defense, weather forecasting, research etc..
False. Only the so-called 'artificial' satellites are man-made. The 'natural' satellites didn't get that name because of the ingredients used to manufacture them. They are called 'natural' because they were created by Nature, not by man. Earth's Moon is an example of a natural satellite, not man-made. There are almost 100 more known examples elsewhere in the Solar System.
about 18,000 man made sattelites are orbiting the earth!
Well, call me a scientist, satellites are sometimes known as ANYTHING that can orbit a rock, star or planet. So, Neptune does have eleven (or more, who knows) moons. Satellites are usually known as the man-made space telescopes, but they can be anything that orbits. Here, let me explain: Planets: Mercury, Earth, Venus... (you know) Stars: The sun Satellites: The moon, Hubble telescope, and other of Earths satellites
non made satellites are those which orbits any planet or star such as earth,moon.
Natural satellites such as moons and man made satellites such as a space station.
There are currently no man made satellites or robots on the planet Neptune.
