The Planet that could End Life on Earth

Experiment demonstrates solar system’s fragility. A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a UC Riverside experiment.

UCR astrophysicist Stephen Kane explained that his experiment was meant to address two notable gaps in planetary science.

The first is the gap in our solar system between the size of terrestrial and giant gas planets. The largest terrestrial planet is Earth, and the smallest gas giant is Neptune, which is four times wider and 17 times more massive than Earth...

A Planet 1,200 light-yrs away is a good Prospect for a Habitable World

Combined climate, orbit models show Kepler-62f might be able to sustain life. The planet, in the direction of constellation Lyra, is ~40% larger than Earth. At that size, Kepler-62f is within the range of planets that are likely to be rocky and possibly could have oceans. NASA’s Kepler mission discovered the planetary system that includes Kepler-62f in 2013, and it identified Kepler-62f, the outermost of 5 planets orbiting a star that is smaller and cooler than the sun. but there was no composition, atmosphere or orbit data.

To determine whether the planet could sustain life, the team came up with possible scenarios about what it...
