Canadian astronomers discover new, volcano-covered exoplanet that may support life The Earth-sized planet, named LP 791-18d, sits on the inner edge of the habitable zone of a red dwarf star about ...

To be clear, the volcanoes on the planet have not been confirmed, but there is some pretty good reason to believe they exist. LP 791-18 d actually has two sibling planets that also orbit the same ...

Scientists will soon be able to study volcanoes on worlds beyond our solar system, according to a new study. Reporting in the Astrophysical Journal, Dr Lisa Kaltenegger, an astronomer with the ...

The closest planet to our sun is Mercury, which has an elliptical, or non-circular, orbit that ranges between 46 million and 69.82 million kilometers (28.5 million to 43.3 million miles) from the sun.

Rather, they inferred it based on the planet's interactions with its neighboring planets. LP 791-18 d orbits between LP 791-18 b, which is around 20 percent bigger than Earth, and LP 791-18 c ...

And, even if it turns out LP 791-18 d does not have any volcanoes or evidence of habitability, astronomers will still be happy to have simply examined a new planet.
