Researchers used software to simulate the planetary motions within a two - planet system: one being a Jupiter - sized planet (depicted in the artist's concept above) orbiting its parent star at about the same distance Earth orbits the sun, and the other a large planet in a highly tilted orbit that was slightly larger.

The discovery was made by Simon Kattenhorn, a geologist previously at the University of Idaho in Moscow, and Louise Prockter, a planetary scientist at the Johns Hopkins Applied Physics Laboratory in Laurel, Md., after looking through photographs from the Galileo spacecraft, which orbited Jupiter from 1995 to 2003.

ALMA studies all phases of planet forming: it probes protoplanetary discs — planetary embryos — at high resolution; it can capture the increasing brightness and temperature of planets in the process of formation and directly detect how giant planets cleanse their orbits within the discs.

We aim at investigating correlations between the host star's mass and the presence of wide - orbit giant planets, and at providing new observational constraints on planetary formation models.

Some of them are orbiting extremely close to their parent star like the 51 Peg planetary system, while others are found to be at distances comparable to where Mars and Jupiter lie in our solar system.

In Kepler's final planetary model, he described planetary orbits as following elliptical paths with the Sun at a focal point of the ellipse.

«The Kepler - 223 planetary system has unusually long - term stability because its four planets interact gravitationally to keep the beat of a carefully choreographed dance as they orbit their host star,» said Eric Ford, a professor of astronomy and astrophysics at Penn State and a member of the research team.

And, «In April 2008, it was announced that two simulations of long - term planetary movement, one at the Paris Observatory and the other at the University of California, Santa Cruz, indicate a 1 % chance that Mercury's orbit could be made unstable by Jupiter's gravitational pull sometime during the lifespan of the Sun.
