   Earth's nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth. Its diameter at its equator is about 7,521 miles (12,104 kilometers), versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.

   How long does it take to see the Sun on Venus?

   • For another, because of the planet's extremely slow rotation, sunrise to sunset would take 117 Earth days. And by the way, the Sun would rise in the west and set in the east, because Venus spins backward compared to Earth. While you’re waiting, don’t expect any seasonal relief from the unrelenting temperatures.

   Does Venus have a subduction zone?

   • Now superheated by greenhouse gases, Venus’ climate was once more similar to Earth’s, with a shallow ocean’s worth of water. It may even have subduction zones like Earth, areas where the planet’s crust sinks back into rock closer to the core of the planet. “Venus is like the control case for Earth,” said Smrekar.

   How far is Venus from the Sun?

   • 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. Earth's nearness to Venus is a matter of perspective.
