Astronomers have discovered five new exoplanets with long periods of revolution around the stars.

Astronomers from the University of Geneva in Switzerland found five new exoplanets with long periods of circulation around the parent stars – more than 15 years. The discovery was made during the analysis of two decades of data collected by the EULER telescope, which is part of the astronomical observatory of La Silla in Chile.

To date, the list of proven exoplanets contains 4,000 copies, most of which are huge worlds that are close to the stars. It is these objects that are easiest to fix, but for scientists, planets that are far from the luminaries are of more interest.

For the EULER telescope, the search for exoplanets is of paramount importance, and it has been doing well for 20 years. Experts say that this unit is able to calculate the speed of rotation of objects around stars with an accuracy of a few m / s and detect planets that are comparable in mass to Neptune.

It is worth noting that all five exoplanets detected by mass exceed the same indicator of Jupiter from 3 to 27 times. The periods of circulation around their "suns" range from 15.6 to 40.4 years. Now astronomers know about 26 exoplanets, whose orbital periods are at least 15 years.
