A research team led by Lund University in Sweden has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more complex than researchers have previously thought.
"The small planet exhibits very unusual orbital behaviour and shows considerable variations regarding the time when it passes in front of its star, which is something that we don't see as a rule. The small planet's existence challenges existing theories on the formation and stability of planetary systems," says Judith Korth, astrophysicist at Lund University and leader of the study.
"Our results will help researchers to learn more about how planets are formed and how they behave when they are very close to each other, particularly in systems with giant planets," says Judith Korth. "I hope that our results can be used in future studies to discover even more planets in other systems, but also to better understand the large range of planetary systems that exist in our galaxy," concludes Judith Korth.Judith Korth, Priyanka Chaturvedi, Hannu Parviainen, Ilaria Carleo, Michael Endl, Eike W.
