Cain's model shows that when Jupiter was closer to the sun about a billion years ago, Venus likely had an eccentricity of 0.3. There would've been a much higher probability that was habitable at ...

Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn't altered its orbit around the sun, ... The number between 0 and 1 is called the eccentricity of the orbit.

Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn't altered its orbit around the sun, ... The number between 0 and 1 is called the eccentricity of the orbit.

Venus today orbital eccentricity near 0.006 and in the model, perhaps moving around near 0.31 and becoming more circular as Venus evolves from near earth-like to the planet we see today.

Venus has an eccentricity of 0.0006 – the roundest in the solar system – while Earth has a value of 0.0167. The model revealed that roughly 1 billion years ago, Jupiter orbited much closer to ...

Venus is now a hellscape, where surface temperatures regularly reach 800 degrees Fahrenheit. Highly acidic rain would give life as we know it an even slimmer chance at survival. But long ago, the ...

An Earth-like planet orbiting a star one-quarter of the mass of our Sun with an eccentricity e > 0.2 in its habitable zone could experience what's called a “tidal Venus” catastrophe.

However, they may have to expand their search since astronomers are now finding asteroids co-orbiting Venus that could pose a threat. ... "There is a range of orbits with eccentricity < 0.38, ...
