Venus is not habitable – and it may be Jupiter’s fault


As a result of Jupiter – the largest planet in our solar system – moving away from the Sun and then closer in its initial formation, the planet’s massive gravitational pull effectively killed Venus’s potential Earth-like environment, according to a study The author was found published in the journal Planetary Science.
According to NASA, Venus is the second closest planet to the Sun, and now surface temperatures are around 880 degrees Fahrenheit (471 degrees Celsius) – above the melting point of lead. It is warmer than Mercury, yet Mercury is closer to the Sun.

Researchers at the University of California, Riverside (UCR) said Jupiter’s movement hastened Venus’ fate as an ineffective planet.

UCR astrobiologist Stephen Kane said in a statement on Wednesday, “As Jupiter escapes, Venus will undergo dramatic changes in climate, then warm up and cool down and rapidly lose its water to the atmosphere.”

“One interesting thing about today’s Venus is that its orbit is almost completely spherical,” said Kane, who led the study.

“With this project, I wanted to find out if the orbit has always been spherical and if not, what are its implications?”

Researchers created a model of the solar system that shows how each planet’s orbit affects each other.

The orbit of a planet is measured between zero and one. Kane said that closer to zero, a more spherical orbit, while an orbit – which is not spherical at all – would also not be able to complete an orbit around a star and would instead launch into space.

Researchers found that when Jupiter was close to the Sun a billion years ago, Venus’s orbit was 0.3, meaning the planet was more likely to be habitable.

However, as Jupiter migrated, it pushed Venus too close to the sun, where it would have undergone a dramatic change in climate, resulting in its current orbit around 0.006 – the most spherical of any planet.

Due to the huge size of Jupiter, it has the ability to disturb the orbits of the surrounding planets; It has a mass that is two and a half times larger than all the planets in the combined solar system.

Venus, named after the Roman goddess of love, is sometimes referred to as the twins of the earth because of their similar size.

A study published last year found that Venus likely maintained a stable temperature and hosted liquid water for billions of years before an event occurred so that the planet undergoes massive changes. Now, it is a mostly dead planet with an atmosphere 90 times more toxic than that of Earth.

Looking for signs of life

According to new research published last month, a gas found on Earth that represents life has also been found in Venus’s atmosphere. The “completely surprising” discovery of phosphine may hint at unknown processes occurring on Venus.

Kane believes it is possible that the gas “may represent the last living species on a planet that has undergone a dramatic change in its environment.”

However, it is unlikely, he said, because those microbes would need to endure for up to a billion years in Venus’ sulfuric acid clouds, as the planet lost liquid water on its surface.

“There are probably many other processes that can produce gas that has not yet been detected,” Kane said.

But understanding how Venus has moved from potentially habitable to inaccessible.

“I said that the differences between Venus and Earth are taken into account, and what went wrong for Venus, so we can get an insight into how the Earth is habitable, and we can make this planet the best it can be. Can do for, ”said Ken.
