Venus is the brightest planet in our night sky! At a distance of only .28A.U., Venus is the closest planet to earth, but Venus' atmosphere traps in such intense heat that it is doubtful that any person will ever land there. Another factor for mankind never having set foot on the closest neighbor to Earth is the intense surface pressure which would make standing on the surface of Venus feel like you were 900 meters deep in Earth's oceans (figure from: NASA).
Unmanned landers that have been sent to Venus have only lasted a few hours before being so effected by the heat and surface environment factors that they no longer operate. The surface temperature of Venus is hot enough to melt lead and this causes the internal mechanics of the landers to not function for very long.
If you were to be standing on the surface of Venus your body would feel slightly lighter than it does on earth because gravity on Venus is about ~91% of the gravity on earth. There is no water on the surface of Venus, and no oceans, but there are slight traces of water vapor in the atmosphere. The atmospheric water vapor never condenses because of the constantly high temperatures the planet experiences.
The atmosphere of Venus is a poisonous mixture of carbon dioxide and sulfuric acid clouds. Consistently fast winds erode the surface much like a wind-blown desert here on earth, producing rolling sand dunes at the base of rocky mountain ranges.
The rotation of Venus is retrograde (exactly opposite) that of earths rotation, and our Sun sets in the east and rises in the west. The clouds on Venus rotate the opposite direction of the normal rotation of the planet, and this phenomenon has been the subject of scientific study and debate as the cause of it is currently unknown.

Things to keep in mind:
- 1 A.U. is the distance from the Earth to the Sun, or 93 million miles ( 149.6 million km )
- Planets have elliptical orbits, and distances given are the average distance from the sun.
- Measurements given in earth terms. If read "days" or "years," earth days and earth years are implied
