New study suggests a planet between Mars and Jupiter could expel Earth and all life.
The Planetary Science Journal published UC Riverside experiment data on Tuesday.
It filled two planetary science gaps, according to UC Riverside scientist Steven Kane.
Gas titans dwarf Earth. Neptune is four times wider and 17 times denser than Earth.
Planetary scientists often wish there was something between those two realms.
Gaps may reveal Earth's evolution and solar system design.
A super-Earth or other celestial object would disrupt all planets due to Jupiter's gravitational drag.
This object could send Mercury, Venus, Earth, and Uranus and Neptune into space.
I underestimated our solar system. Predictably. "Gears ruin it," Kane said.
