The first of two spacecraft to visit the planet was Mariner 10, which has mapped about 45% of the planet's surface from 1974 to 1975. The second is the MESSENGER spacecraft from NASA, which mapped another 30% during his trip to Mercury January 14, 2008. MESSENGER is now in orbit around Mercury to complete the mapping.
Only two spacecrafts have visited Mercury so far: Mariner 10 in the 1970s and MESSENGER, which orbited the planet from 2011 to 2015. The European Space Agency and the Japanese space agency are planning a joint mission called BepiColombo to Mercury, which is set to launch in 2022.
Two spacecraft have visited the planet Mercury so far. The first was called Mariner 10. During 1974 and 1975, Mariner 10 flew by Mercury three times and mapped about half of the planet's surface. Mariner 10 also discovered Mercury's thin atmosphere and detected its magnetic field. More recently, Messenger went into orbit around Mercury in 2011, and completed mapping of 100% of Mercury's surface in 2013. BepiColombo is planned for launch in 2015 and planned to enter orbit around Mercury in 2022. Source: http://coolcosmos.ipac.caltech.edu/ask/31-How-many-spacecraft-have-been-to-Mercury-
it has neither. also there are no man made orbiting spacecrafts.
As of now, there are no artificial satellites orbiting Venus. Only spacecrafts have been sent to Venus for exploration and research.
Spacecrafts studying Mercury have revealed a variety of fascinating findings. Some notable discoveries include its heavily cratered surface, presence of water ice in permanently shadowed craters, a large iron core contributing to its strong magnetic field, and extreme temperature variations with highs of over 800 degrees Fahrenheit.
saturn has only been visited 4 times by spacecrafts
As of 2021, only two spacecraft have visited Mercury: Mariner 10, which flew by three times in the 1970s, and MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), which orbited the planet from 2011 to 2015. The European Space Agency's BepiColombo mission is currently en route to Mercury as well.
mariner 10 and MESSENGER
Planets that have been visited by spacecrafts include Mars, Venus, Mercury, Jupiter, Saturn, Uranus, and Neptune. Additionally, the spacecraft Voyager 2 has conducted flybys of both Uranus and Neptune.

Although several spacecrafts have been sent to Venus, no alien spacecrafts have been discovered on its surface.
You seem to be misinformed. The first US spacecraft was Mariner 10. This was followed by Messenger. There have not been others.

Venus has acid that melts metal. It is also hotter than Mercury because of Venus's clouds.
Yes. We have landed multiple probes and rovers on Mars.
