Venus is the second planet from the Sun, orbiting at a distance of .72 AU. It has no natural satellites.
A moon? I don't think a planet orbiting another planet would be called a planet.
Yes, we have satellites orbiting mars. The last few probes that we've sent contained both landers and satellites intended to orbit the planet. They not only photograph the planet but they also serve as relays and retransmitters for the landers when communicating with Earth.
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
A planet doesn't "have planets". Anything orbiting a planet is called a moon, or a satellite.
Venus is the biggest planet in our solar system that has no known satellites (moons).
Planets are not considered satellites, but rather celestial bodies that orbit around stars, like our Sun. Satellites are objects that orbit larger celestial bodies, such as planets orbiting around stars or moons orbiting around planets.
A natural body that rotates around a planet is a satellite, as in a moon. Man made satellites (artificial satellites) are made mostly of metal and rotate around earth looking at weather patterns or orbiting other planets for information. When they say Neptune has eleven satellites, they mean moons orbiting the planet, not man made ones. There doesn't have to be anyone there for there to be satellites of both kinds there.
A lump of rock orbiting around a planet is called a moon. Moons are natural satellites that typically revolve around planets in our solar system.
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

A satellite is an object that orbits a planet. The Sun is a star so it does not have satellites. Actually a satellite is anything that orbits another. So the planets and asteriods are the sun's satellites.
