The planets, each larger than Jupiter, circling a young star in the constellation Pegasus.
It comes as the result of seven years of observations at the W.M. Keck Observatory in Hawaii, gives an interesting picture of the four planets orbital period in a relationship that is almost right with the other.
The animation was created by Jason Wang, a graduate student in astronomy at the University of California, Berkeley, based on observations of four of the eight planets, dating back to 2009.
Their star, HR 8799, have fewer than 60 million a year and nearly five times brighter than the Sun, according to much of the world.
These objects have orbits that are very different, more than 400 for 40 years.
But the researchers believe that they are in resonance one-two-4-8.
This means that their orbital period is almost accurate reports in one with others.
Considering how long it takes the planet to complete each orbit, only excerpts of this journey is shown in the animation.
Astronomers have discovered three planets HR 8799 in 2008, using the direct imaging for the first time.
The team included Christian Marois of the Herzberg Institute of Astrophysics National
Research Council, who analyzed the data, according to much of the world.
Scientific graphics then the first planet HR 8799, a separate team also announced a direct image of a planet in orbit around the star Fomalhaut.
After additional comments in 2009-2010, researchers found fourth planet around HR 8799.
Wang used a motion interpolation algorithm to draw their orbit, and the animation shows this four stars which they make their way around HR 8799.
Researchers have created a similar animation of the planets in orbit around Beta Pictoris.
According to Wang, the new technique "allows us to use the data reduction process of artifact we use to consider interruption to further limit the planetary positions.
So they look, researchers have been blocking the light from a star, causing the black circle in the Center.
Each star is larger than Jupiter and thus very far from each other.
While researchers continue to observe this system, they will look to see if the stable, or if several planets will be issued.
Wang and Maori was part of the Gemini Planet Imager operating team, an additional in Gemini South telescope in Chile.
THE EXOPLANETS
Each star is larger than Jupiter, and thus lie far away from each other.
As researchers continue to observe this system, they will watch to see if it is stable, or if some of the planets will be ejected. Their star, HR 8799, is less than 60 million years old and is nearly five times brighter than the sun. Their orbital periods vary from 40 years to more than 400, but researchers suspect they are in a one-two-four-eight resonance with each other. This means their individual orbital periods are in nearly precise ratio with the others.
