Scientists have discovered a miniature planetary system.
Astrophysics from the USA, Britain and Israel have discovered an unusual system in which exoplanets are extremely close to the sun.
A study published in the journal Astronomical Journal, briefly about it, reports the Florida Institute of technology.
Around the star Kepler-80 five exoplanets rotate with periods of 1, 3, 4, 7 and 9 earth days. They are all located to the sun is 150 times closer than Earth is to the Sun, and extremely close to each other. The four outer planets 4-6 times heavier than Earth, and closest to Kepler-80 celestial body is almost two times more than others, because they have a huge hydrogen-helium atmosphere.
The outer four planets are in orbital resonance to each other. Dynamics returns to its original state every 27 days. The system Kepler-80 is at a distance of 1.1 thousand light-years from Earth in the constellation Cygnus. Luminary is an orange dwarf, which is 1.5 times less than the Sun.
The exoplanet was discovered in 2012 by the space telescope Kepler. As a result of recent studies, scientists have confirmed the unusual nature of the system and clarified its orbital characteristics.
