Speeding Gas Giant Recently Located!

Playing peek-a-boo with a planet; I never would have thought about it.  I suppose that could be a way to describe how scientists are locating this particular world that is so far away.  More and more extrasolar planets are being identified, as this one was found through a unique method!

The star KOI-872 is similar to The Sun.  It is within our Milky Way, situated near the constellation Cygnus.  This constellation also contains the double-star system Albireo, and the star Deneb.

The planet that has been designated as KOI-872b orbits KOI-872 at a rate of once for every 34 Earth days.  This world is roughly 83 million miles away from it’s host star, comfortably located within a habitable zone.  It is eighty percent the size of Jupiter.  Scientists with The N.A.S.A. Ames Research Center seemed to confirm this planet’s existence during the 2010 Christmas season.

Additionally, studies are showing that KOI-872c, the second world out from this star, also races around in it’s orbital path.  872c revolves around KOI-872 once every 57 Earth days.  I am speculating that due to these worlds being gas giants, there is no solid mass to keep them from moving at slower rates.  The gravitational power of KOI-872 allows it to sling it’s worlds around at high speeds because they are gaseous worlds at close distances to this star.

Indeed, studying scientists speculated that KOI-872b was moving so fast because another world had to be further out, pulling on the planet.  Thus, KOI-872c was revealed, showing that it’s gravitational forces were behind the rapid movement of that star’s inner-most world.  Yet, I still am looking for why these planets are moving so fast! 

Scientists were able to discover these worlds through using old, yet proven techniques.  Each was located by shifts in their orbits, which indicated that gravitational forces were in action, causing the worlds to move with signs of being pulled upon.  Indeed, it was over 150 years ago when French mathematician Urbain Le Verrier predicted the presence of Neptune because of unseen forces tugging on Uranus (no, not yours…. the planet…)!

KOI, the label designated to several newly-identified stars and worlds, stands for Kepler Object of Interest.
