1. No planet is known to be formed of frozed water. Pluto (now called a dwarf planet) might be, though.
2. No planet has a water vapor atmosphere (although Earth has a lot of it in the atmosphere). One of the moons of Neptune has water vapor geysers, however (I think it is Triton, but it may be Nereid).
3. Mars (Olympus mons)
4. Venus (by far)

Sorry, B-Man, I'll argue some of your answers.
Planet mostly frozen water would be Pluto (even though its now a dwarf planet). If you consider satellites, then almost all of Saturn's, Jupiter's, and Uranus's moons would qualify.
Water vapour atmosphere - Earth.
Largest volcano - probably Mars (Mons Olympus)
Brightest planet - Venus at its brightest is a tiny bit brighter than Jupiter. The main reason people choose Jupiter is that its often visible in the middle of the night so it appears brighter than Venus, which is only visible an hour or so before sunrise or after sunset.

1. Pluto is the one mostly made of frozen water, but now that it's not a planet, I'd say Mars. Since Neptune and all the Jovian Planets are made of gas.
2.Earth?
3. Olympus Mons on Mars.
4. Venus.
Hope this helps.

human beings have purely set foot on earth and the moon. not one of the different planets have had human beings on them, although we've sent probes and landers to the a number of worlds.... Mercury has had a pair of Mariner fly-bys, and at present has Messenger orbiting the planet. Venus has the Russian Venera landers (i think of 9 have been sent, and four touched down and truly returned pictures and archives for a quick quantity of time.) united statesa. sent the Pioneer-Venus probe, with 4 atmospheric probes that *did* land, yet they weren't designed to land softly. Venus has had a pair of orbiters as properly. Mars - it extremely is had MANY missions sent, yet purely a pair of million/2 are valuable. we've landers and rovers on the exterior, and various of different orbiters. Jupiter - we've sent one orbital probe, Galileo, that still dropped an atmospheric probe into Jupiter's environment. The Voyager and Pioneer craft did fly-bys as properly. Saturn - we've sent one orbital probe, Cassini, that still dropped a probe onto the moon Titan. The Voyagers and Pioneer eleven did fly-bys as properly. Neptune and Uranus have had the Voyager fly-bys purely. Pluto has on no account been visited, yet there's a probe en course - stated as New Horizons - which will do a fly-by skill of in 2015.

venus has th elargest volcano: olyumpus mons
earths atmosphere is not compleately composed of water vapor but it has a lot of it in it. and i think that pluto( now a dwarf planet) is composed mostly of frozen water! last one i am not sure about sorry!
