Two striking features are the continent-sized highland areas, or terrae—Ishtar Terra in the northern hemisphere and Aphrodite Terra along the equator. Ishtar is roughly the size of Australia, while Aphrodite is comparable in area to South America. Ishtar possesses the most spectacular topography on Venus. Much of its interior is a high plateau, called Lakshmi Planum, that resembles in configuration the Plateau of Tibet on Earth. Lakshmi is bounded by mountains on most sides, the largest range being the enormous Maxwell Montes on the east. These mountains soar about 11 km (7 miles) above the mean radius of Venus. The topography of Aphrodite, more complex than that of Ishtar, is characterized by a number of distinct mountain ranges and several deep, narrow troughs. In addition to the two main terrae are several smaller elevated regions, including Alpha Regio, Beta Regio, and Phoebe Regio

All planets go round the sun in the same direction,but they do not all spin in the same direction. Earth's axis is tipped 23.5 degrees relative to its orbital axis.Uranus is tipped 98 degrees and venus is tipped 177 degrees.So, astronomers say that venus spins 'backwards'.Mercury and Venus spin very slowly when compared to other planets.One day on venus is equivalent to 243 days.Its time of rotation is more than its time of revolution(225 days) around the sun.Moreover it has no moons.It is a perfect sphere with the equatorial radius and polar radius being almost equal.

Venus is approximately the same size as Earth and has been nicknamed "Earths 'Evil' twin" as it has been cited as an example of runaway global warming. It has no moons, a toxic, acidic atmosphere (it rains sulphuric acid). Has high levels of radiation and high atmospheric pressures.

It is a planet whose day (rotational period) is longer than its year (siderial period). It has a high albedo (reflection of light) due to the large cloud cover there, and also has a very toxic environment.
It is the second planet from the sun, no moons or major satellites, with a rocky core...
Hope this helps.
