Amateur Team Finds 'Tatooine' Planet with 2 Suns in 4-Star System
Amateur astronomers have helped discover an alien planet with two suns and a twinkling twist: The entire twin-sun setup, a real-life version of Tatooine from "Star Wars," is orbited by two more stars — a solar system that is the first of its kind known.

Since its initial discovery via Planet Hunters, the existence of PH1 has been confirmed by a team of professional astronomers, who will present their work today (Oct. 15) at the annual meeting of the Division for Planetary Sciences of the American Astronomical Society in Reno, Nev.

With a radius about 6.2 times that of Earth's, PH1 is a smidge bigger than Neptune. The gassy planet spends 138 days completing a single orbit around its two parent stars, which have masses about 1.5 and 0.41 times that of the sun. The stars circle each other once every 20 days.

The two other stars orbiting the PH1's twin suns are about 1,000 astronomical units (AU) from the parent stars. (One AU is about the distance between the Earth and sun, about 93 million miles or 150 million kilometers.)

If you're hoping to catch the quadruple sunset, this may not be your best bet. The researchers estimate PH1's temperature would range from a minimum of about 484 degrees Fahrenheit (524 Kelvin, or 251 degrees Celsius) and a maximum of 644 degrees F (613 Kelvin, or 340 degrees C), too hot to be in the habitable zone.

Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System

(Submitted on 12 Oct 2012)

We report the discovery and confirmation of a transiting circumbinary planet (PH1) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunteers searching the first six Quarters of publicly available Kepler data as part of the Planet Hunters citizen science project. Transits of the planet across the larger and brighter of the eclipsing stars are detectable by visual inspection every ~137 days, with seven transits identified in Quarters 1-11. The physical and orbital parameters of both the host stars and planet were obtained via a photometric-dynamical model, simultaneously fitting both the measured radial velocities and the Kepler light curve of KIC 4862625.The 6.18 $\pm$ 0.17 Earth radii planet orbits outside the 20-day orbit of an eclipsing binary consisting of an F dwarf (1.734 +/- 0.044 Solar radii, 1.528 +/- 0.087 Solar masses) and M dwarf (0.378 +/0 0.023 Solar radii, 0.408 +/- 0.024 solar masses). For the planet, we find an upper mass limit of 169 Earth masses(0.531 Jupiter masses) at the 99.7& confidence level. With a radius and mass less than that of Jupiter, PH1 is well within the planetary regime. Outside the planet's orbit, at ~1000 AU, a previously unknown visual binary has been identified that is bound to the planetary system, making this the first known case of a quadruple star system with a transiting planet.

The same claim to have found 'caveman' yet one hoax after the next has been exposed and still no 'caveman'.

NASA gives us one alleged direct image of an exoplanetary system, and based on little more evidence claims there are over 600 planets discovered since Hubble was launched in 1990.

Interesting the movies have been spreading ET planets since the 1950s.

Until they get more evidence these claims are unconvincing.

again this bullshit. why cant they not first look here ad try to understand our solar system or our neighbour at least alpha centauri or sirius.

always this far far away stuff and then its uninhabitable. fuck them. then I dont want to know and many others dont give a fuck about this shit.

Kinda hard to stand and admire the twin sunset and ponder life while you're enveloped in bone crushing pressurized gasses.

Just sayin....

Banned as usual.

“It is far easier to be a weakling than to be a Real Man. Were the Earth less harsh or the circumstances of life less austere, man would destroy himself before the shrine of the languid goddess. Only Real Men can with safety destroy the tangled forests and wilderness of Earth and make from them gardens, but will those who inherit the gardens be Real Men? The law decrees that they must be, or the wilderness will reclaim its own.”

...you sell yourself way short,we are all spirit within our arks and we as spirit existed before the creation...to use a created concept to describe us all would be co-creator spirits whom share the same life giving to the ark spirit...we existed before religious concepts also hf..there is us as spirit and there is the creation/creations, their is nothing else...one or the other and the creation did not create our spirit...it has always existed and will always exist not in just one temporary ark as we move from place to place and mostly lose our memories until we realize whom we were and are again within our arks and whom we will be next incarnation into the creation...

This is just my favorite stuff of the modern age. We are scanning the stars for interesting stuff. It's been done in the past, but with the new tools, it's just real exciting for any who love exploration and the great unknowns.
