New 'Gas Dwarf' Class of Alien Planets Revealed
NBC ^ | Nola Taylor Redd, SPACE.com

Posted on 06/02/2014 1:51:22 PM PDT by BenLurkin

These gas-dwarf alien planets have thick atmospheres like their larger gas-giant cousins but never quite made it to the size of the planetary behemoths found in the Earth's the outer solar system, researchers said.

The team studied more than 600 planets discovered by NASA's Kepler space telescope and compared their sizes to the amount of elements other than hydrogen and helium contained in their star — a characteristic known as metallicity.

"We were particularly interested in probing the planetary regime smaller than four times the size of Earth, because it includes three-fourths of the planets found by Kepler," lead author Lars A. Buchhave, of the Harvard-Smithsonian Center for Astrophysics (CfA), said in a statement. He presented the findings today (June 2) here at the 224th meeting of the American Astronomical Society in Boston. [7 Great Exoplanet Discoveries by NASA's Kepler]

"That's where you'll find rocky worlds, which are the only kinds that we would consider potentially habitable," Buchhave said.

The team found clear dividing lines at the planets that were between 1.7 and 3.9 times the size of Earth. These boundaries likely mark changes in composition as well: Planets smaller than 1.7 Earths are likely to be rocky terrestrial bodies, while those 3.9 times larger are apt to be gas giants, the researchers said.

Hey, if it can make a sheet ruffle, can I qualify for a ‘gas dwarf’ exemption next year? Tiny of force and stature but still worthy of note.. Unless your cats sleep under the blanket.

They aren't "alien planets"...they are "undocumented planets."

How insensitive can they get? Sheesh!

Will liberals boycott NBC for using the words dwarfs & alien? Did NBC not get the note that those are banned words?
