   Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.

   At its nearest to Earth, Venus is some 38 million miles (about 61 million kilometers) distant. But most of the time the two planets are farther apart; Mercury, the innermost planet, actually spends more time in Earth’s proximity than Venus. One more trick of perspective: how Venus looks through binoculars or a telescope.

   Could solar energy be collected from Venus?

   • Venus would also need to be cooled down from the scorching sun using some kind of  sun shade, which has the side effect of collecting solar energy for potential human or robotic use. The sun-observing Solar Orbiter spacecraft makes regular flybys at Venus, taking measurements of the planet's magnetic field as a side project. (Image credit: ESA)

   What can Venus teach us?

   • There is much, it would seem, that she can teach us. Venus orbits the Sun from an average distance of 67 million miles (108 million kilometers), or 0.72 astronomical units. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight about six minutes to travel from the Sun to Venus.

   What was Venus like in the past?

   • It is possible that Venus was more like Earth in the past, with habitable surface temperatures and oceans of water perhaps up to 300m (984ft) deep (Earth's mean ocean depths are 2700m/8850ft), but over time, the histories of these planets were driven apart. There are key differences between modern Earth and Venus.
