Once a violent hot D-Class world, hundreds of years of terraforming has turned this world into a temperate E-Class tropical paradise. Venus, the second planet in the Sol System now has a mean temperature of around 25 °C (82 °F), a day length of 23 hours and 28 minutes and an atmospheric pressure - and approximate gravity - of 0.9 times Earth's at sea level.
The first humans to ‘settle’ Venus in 2042 were scientists who lived on small floating dirigible cities high above the clouds. They studied the planet for decades before they were forced to evacuate when terraforming began.
Terraforming began in 2065 with orbital bombardment: nudging asteroids into orbit and slamming them at an angle to speed up the planets rotation. About half of these were massive ice asteroids while most of the other half were made of carbon, both of which helped introduce water vapor into Venus’s atmosphere. At the same time massive reflective plates were deployed within the planet’s atmosphere to cool the planet’s atmosphere - no attempt was made of reducing the carbon dioxide in the atmosphere, as it was considered difficult and impractical. Slowly the planet began to cool and speed up. As it was too much work to reverse the planet's retrograde (reversed) rotation - and doing so gave so little reward - they left it, meaning that when seen from the surface, Sol rises from west to east.
As human technology advanced, so did the methods for terraforming. Instead of the mirror solution, they were able to alter the atmosphere - the cause of Venus's high temperature - reducing the CO2 levels dramatically. By the year 2300, Venus had a barely breathable atmosphere of 0.9 atmospheres and a day length of around thirty days. By this time the technology to move other worlds had become so advanced that it was now possible to move Mercury into Venus's orbit. This allowed its day/night cycle to stabilize. Moving Venus into Earth's orbit was considered and quickly abandoned, due to its sheer mass, and the large distance that they would need to move it. With Mercury out of the way, Venus became the first planet in the Solar System - a title it held until the introduction of Vulcan in 3021.
By the year 2500 Venus had become a virtual tropical paradise. The mainland, the continent of Aphrodite, is where the majority of Venusians live - even this has not changed over all these years.
As stated above, the mainland of Venus, the equatorial continent of Aphrodite, is where the majority of the 21.3 billion descendants of the first human colonists live. Many of the first colonists to begin to settle the planet came from many of the equatorial Earth countries, like Africa, Central and South America, and Oceania. Of course many others came to live there as well, but most came from those areas. Over the many thousands of years, the Venusian’s skin has darkened to accommodate the increase in sunlight. No other major changes have happened - Venusians are considered in the same subspecies as Earthlings (or Terrans).
Venus, being closer to the Sun, is a largely warm tropical world. Due to the slightly lower gravity, transplanted tropical trees grow a bit taller than they would on Earth; animals are also a bit more agile and taller. Venus also has more of a cloud cover than Earth does, most of which are large rainstorms.
Venus does have a few deserts which is where many Arab colonists set up their own caravans.
Thanks to careful planning, cities on Venus do not give off much light pollution at all, leaving the night side of the planet mostly dark. Venus is the second most populous world in the Sol sytem - second only to Earth.
