Why some planets orbit backwards?

Experts from Northwestern University in Illinois, USA, conduct a study that was published in the scientific journal Nature, and which required to find the reasons for this phenomenon that breaks with the standard theory of planet configuration. According to this theory, a planet must rotate in the same direction as their star, just like in our solar system. "It's very strange, and it is even rarer because the planet is very close to the star," said Frederic Rasio, an astrophysicist at Northwestern University.
