I meant planets any country has actually landed on.

If you mean landing on another planet, yes just Mars and Venus.
However, flybys have been done of all the planets except Pluto.

The Soviet Union did land some actual spacecraft on Venus, which operated for a few minutes (and sending back photos) before their circuits & battery melted.
NASA did land one probe on Venus in 1978, but it was not a soft landing and probably made a nice crater. To their credit though, they've landed a bunch of great probes on Mars, & one on Titan.

Every planet has been visited, at least by fly-bys, except for Pluto, and the New Horizons craft is heading there right now for a 2015 rendez-vous.
Mars and Venus have been the most commonly visited (including landings). Jupiter and Saturn a few times. Mercury, Uranus, and Neptune just once.

Planets:
Venus - Soviet Venera mission.
Mars - several US missions the first being Mariner
Now, we have sent probes into Jupiter, but it was crushed by pressure before it got anywhere near the center. Although it being a gas giant, there may truly be nothing to land on.
The US has sent several probes to moons as well. Not just our own with the Apollo missions, but we just recently went to Titan with the ESA's probe on the US Cassini mission.
So, I guess it would depend upon what you define as planet or if you just want to quantify it as "extraterrestrial body".

True, but we just landed a probe on Titan - one of Saturn's moons. That's over a billion mile journey. And it actually sent back pictures for a little while before it froze in the -270 degree temperature. Amazing snapshots of a world bigger than our moon, with what might be methane lakes and a slushy methane ice surface. Are we good or what?

all have been visited or closely flown by with the exception of pluto.these were all unmanned spacecraft.the only heavenly body to be visited by a manned spacecraft was the moon, but plans are in the works to try a manned voyage to mars in the future.

only landings on mars, venus and titan (saturn's moon), I think we have an orbiter around mercury but no landings, and yes fly by's of most of the planets. oh yeah and we crashed a probe into that asteroid.

If you mean landed on, yes, only Mars and Venus, but if flying by counts no. Voyager has flew by Mars, Saturn, Jupiter, Uranus, and Neptune.

yes, mars and Venus as far as landing, but all of them have been from Voyager.It is now moving out of our solar system toward the nearest of stars.

Voyager has had close fly-bys of nearly all the planets.
