Feb 3, 2020 · The facile answer is "Venus's atmosphere has many times the mass of Earth's atmosphere because it has many times the amount of gas". Which makes us ask wonder why that is. Many planetary scientists have interpreted the relatively even distribuion of impact craters on the surface of Venus as a sign that the planet was resurfaced in some catastrophic event 500-700 million years ago:
Oct 1, 2018 · Therefore, Venus preserves much more of this early record than Earth, and a much richer record, including spatial clues. In contrast, Earth preserves geochemical clues currently inaccessible from Venus. Collectively, clues from both sisters will provide a more comprehensive understanding of early terrestrial planet geodynamics.

Venus is similar to Earth in size and density, and so probably also in bulk composition, but it does not have a significant magnetic field. [7]: 1729–1730 Earth's magnetic field is produced by what is known as the core dynamo, consisting of an electrically conducting liquid, the nickel-iron outer core that rotates and is convecting.
Apr 7, 2016 · Basically, Venus orbits closer to our Sun and with an eccentricity that is less than one-third that of Earth’s (0.006772 compared to 0.0167086). In addition, Earth’s axis is tilted far more ...
Oct 26, 2023 · If true, that suggests Venus could have been much more like Earth in other ways. The geochemical reactions of plate tectonics could have buried much of the carbon dioxide that makes Venus so ...
May 23, 2024 · O’Rourke et al. provide an overview of the planet Venus, from the dawn of the Space Age to the recent history of space missions, basic properties of the atmosphere, surface and interior; and recent advances in Venus-related theory and modeling; it explores big-picture hypotheses for how Venus may have evolved over time, and sets the stage for the rest of this topical collection—providing ...

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.
