Dec 11, 2019 · 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.
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.
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.
Oct 31, 2023 · However, a new study looks at the link between Venus’s atmosphere and interior, and concludes that an ancient phase of plate tectonics, lasting at least 1 billion years, must have occurred in ...

Mar 2, 2015 · Understanding why Venus and Earth became so different will help us understand why Earth evolved as it has and what the range of conditions for similarly sized worlds around other stars may be. Venus provides the contrast to the Earth that can help us both better understand the origins of our world’s characteristics and the range of possibilities for similar sized planets orbiting other stars.
May 18, 2023 · On Venus, deuterium is about 100 times more prevalent than on Earth. This indicates to some researchers that Venus must have once had vastly more hydrogen — most likely in the form of water, and ...
Oct 26, 2023 · Venus, on the other hand, Earth’s nearest neighbor and sister planet, went in the opposite direction and today has surface temperatures hot enough to melt lead. One explanation is that the planet has always been thought to have what’s known as a “stagnant lid,” meaning its surface has only a single plate with minimal amounts of give, movement and gasses being released into the atmosphere.
