Backward Orbiting Planets Puzzle Scientists
It is what you call breaking the convention.
Six of the 27 planets found in distant solar systems were observed to be orbiting in the direction opposite their star’s rotation.
“The new results really challenge the conventional wisdom that planets should always orbit in the same direction as their stars spin,” says astronomer Andrew Cameron of the University of St Andrews. His team’s research results were presented at the Royal Astronomical Society meeting in Glasgow, Scotland.
Another conventional view being rocked by the discovery is the one that states that planets are formed by the condensation of dust from a disk surrounding a newly formed star.
Meanwhile, some of the planets have highly tilted orbits, another convention breaking finding.
All of the findings also suggest that orbits would destroy any smaller, rocky planets. This will mean that an Earth-like planet orbiting around a star would be unique in that solar system.
