"Instead of being a sweltering and waterless rocky world, Venus could very well have been a habitable planet had Jupiter not altered its orbit around the Sun a billion years ago, a new study has found.
In early September 2020, potential indicators of life were discovered on Venus, when scientists detected the presence of phosphine on its clouds. However, as of now, Earth’s sister planet remains a world that is not conducive to life as we know it, and the biggest planet in our solar system might be the one to blame for this shortcoming.
Jupiter, which is two-and-a-half times more massive than all the other planets in our solar system combined, and voluminous enough to fit 1,321 Earths inside it, possesses the ability to disturb other planets’ orbits around the Sun."
