Spacecraft from Earth have indeed been sent to Venus - in fact the first one to land on another planet was the Russian Venera 7 probe in the 1970s, along with several others in that series, and later Venera 9 which was Venus's first artificial satelite (orbiter). The USSR continued to send probes in the 70s and 80s including the Vega series. The United States also sent the Mariner series which included close approaches (flyby), and later the Galileo, Magellin, and Messenger probes for global mapping and gravity assists for later destinations. In the 1990s the ESA got on the scene with separate or joint projects like Cassini and Venus Express. Japan also sent several missions including two orbiters.

The exploration of Mercury has taken only a minor role in the space interests of the world.
It is the least explored inner planet.
Mariner 10 was a probe whose primary objective was to observe the atmosphere, surface, and physical characteristics of Mercury and Venus.
It was a low-cost mission completed for under $98 million.
Mariner 10 was launched at 21:45 PST on November 2, 1973, from Cape Kennedy.
MESSENGER is a probe launched by NASA that is currently en route to Mercury.
MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging.
It was launched from Cape Canaveral on August 3, 2004, after a two-day delay due to bad weather.
To correct the speed of the satellite it undertook gravitational slingshot flybys of planets several times.
It passed by the Earth in February 2005 and then Venus in October 2006 and in October 2007.
The total travel time before entering orbit is about six and a half years.
Before entering orbit in 2011, the probe made three passes of Mercury.
As of 2008, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury.
MESSENGER made a fly-by of Mercury on 14 January 2008, to further investigate the observations made by Mariner 10 in 1975.
Yes, Saturn has a man-made satellite named Cassini. It was orignally sen to observe Saturn's largest moon Titan, but has now studied many of Saturn's other moons. Cassini was originally launched in 1977 and has drastically biggered our understanding of Saturn.
There id been 7 satellites sent to Jupiter, that's my guess
um soz I don't quite know all of them but Galileo spacecraft and voyager 1 spacecraft
Yes, there are a couple of man-made satellites orbiting Venus.
how many man-made satellites have been sent to the planet mercury how many man-made satellites have been sent to the planet mercury
New Horizons is on the way to Pluto, which it should reach in July 2015, though it will only pass by and not land on it, as it is continuing on to the Kuiper Belt.
yes 10 of them

Yes, two probes have been sent to the planet so far (2015).
No natural satellites of Mercury have been discovered.
Yes by two satellites. Mariner 10 in 1974/75 which mapped about 45% of the planet, and Messenger in January 2008 which added another 30%. Messenger is due to make two more passes of Mercury before finally orbiting the planet in 2011.
no, mercury and venus are the only two planets that do not have moons.
As of early 2010, more than 265 natural satellites have been identified in the solar system, orbiting every planet except Mercury and Venus.
Since Earth's Moon was likely formed from a chance collision, the formation of moons may not have been a stable process in the inner solar system. Any moons that formed around Venus or Mercury could have been swept away by the stronger gravity of the Sun, as might smaller moons around Earth. If Mercury or Venus ever had satellites, they were lost long ago.
No natural satellites of Mercury have been discovered.
No natural satellites have been discovered in orbit around Mercury. Planetary scientists are by now quite firmly convinced that the planet has no moons.

None. The planet had been observed by ancient astronomers by the 14th Century BC - so almost 3,500 years ago. Thus Mercury had been discovered a very long time before the first satellites were even dreamt of.
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.
Natural satellites have been observed in orbit around every known planet in the solar system EXCEPT Mercury and Venus.
No satellites have been discovered yet in orbit around Mercury. As of now, the answer to the question is zero.
