Yes they have had a few. The 2 were not man made but the other one was. Its called Ozonicsam.
Since we live ON the Earth, all satellites WE have sent have been sent FROM the Earth, and circle around it.
what made the tracks on planet mercury is rover, the space robot, who was sent from the nasa space station to look for any sign of human life on planet mercury.
Natural satellites? none. Uranus - 27 known moons to date Jupiter - 63 known moons to date Saturn - 60 known moons to date Mercury - 0 Mars - 2 Earth - 1 Neptune - 13 known moons to date Pluto - 3 known moons to date Venus - 0 None because Mercury has no moons/satellites at all.
Technically a satellite is something in orbit around a planet, so there cannot be any satellites ON Mercury. I will assume you mean satillites in orbit around Mercury. Mariner 10 was the first probe sent to Mercury, however it orbited the sun (i.e. was not technically a satellite of Mercury) however it's prime purpose was to observe Mercury. The probe MESSENGER and the two probes from the BepiColombo mission are currently the only satellites orbiting Mercury.
john William has explored the planet mercury... but no one has been sent out to this planet
The primary spacecraft sent to Mercury are NASA's Mariner 10, which made three flybys of the planet in the 1970s, and the MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) spacecraft, which orbited Mercury from 2011 to 2015. Additionally, the European Space Agency's BepiColombo mission, launched in 2018, is currently en route to Mercury and consists of two spacecraft: the Mercury Planetary Orbiter and the Mercury Magnetospheric Orbiter. As of now, there are no robots or landers on Mercury's surface.
No
Jupiter has natural satellites, also known as moons, as well as robotic satellites sent by humans to study the planet. Robotic satellites, such as the Juno spacecraft, have been used to gather data and images of Jupiter to enhance our understanding of the planet.
there has been 7 man made satellites sent to Saturn.
The Mariner10 space probe and the Mercury Messenger space probe.
Venus has no natural satellites but probes have been sent their for many years now.
There are no plants on Mars. We know this because of the rovers we have sent and the satellites we have taking pictures of the planet.
