Get Ready For The 100-plus Planet Solar System

EXCERPT: Pluto’s status as a non-planet may be coming to an end. Professor Mike Brown of Caltech ended Pluto’s planetary status in 2006. But now, Kirby Runyon, a doctoral student at Johns Hopkins University, thinks it’s time to cancel that demotion and restore it as our Solar System’s ninth planet. Pluto’s rebirth as a planet is not just all about Pluto, though. A newer, more accurate definition of what is and what is not a planet is needed. And if Runyon and the other people on the team he leads are successful, our Solar System would have more than 100 planets, including many bodies we currently call moons.

Young Solar System 300 Light-Years Away Shows Scientists How Planets Evolve

EXCERPT: Astrophysicists observing a freshly formed solar system nearly 300 light-years away from our home planet had the fortuitous chance to uncover planetary evolution in its ending stages. The insight came from studying a large new planet, very similar to Jupiter but 11 times more massive and discovered just three years ago by American, Dutch, and Italian scientists. Known as HD 106906b, the planet is extremely young by celestial standards: barely 13 million years old, as opposed to 4.6 billion years, the age of our solar system. "We have a snapshot of a baby star that just formed its planetary system - a rare peek at the final stage of planet formation," said study co-author Smadar Naoz, a physics and astronomy assistant professor at the University of California, Los Angeles....
