This star system consists of 5 potentially habitable planets
A team of Astronomers from the University of Montreal have discovered a potentially residential planet that is rotating the red dwarf star L 98-59, 35 light-years from Earth. The discovery means that there are now five approved planets in the “temperate” or “habitable” area of the Solar System, an area in a solar system where liquid water can exist on planetary surfaces.
The newly discovered planet called “L 98-59 F” managed to escape the previous observations because it does not pass between the earth and its star during the orbit, known as “transfer”. The planets that convey their host stars are more comfortable to pay attention to, as the mini -liptes that create their star’s face are seen by telescopes.
Research on the discovery of the planet – which is waiting for the publication of Astronomical Magazine– He landed the planet through the subtle changes to his host star’s movement. The planets move in the orbit of the stars as they move their orbit to their hosts and move their star position slightly. These movements can show the presence of planets even if they do not see them.
The explicit movements of the L 98-59 are harvested by two tools designed for hunting planet: HARPS spectrum, installed in the Southern European Observatory Telescope (ESO), and Exoplanet Exoplanet Rocky, which is part of a very large telescope (VLT).

The L 98-59 F stands from other planets in its solar system because it receives a similar amount of solar energy to Earth. According to Montreal researchers, if it has the right space, it can be a temperate planet that can preserve liquid water on its surface.
In addition, the possibility of liquid water is a habitable area of the solar system that can potentially enable planetary conditions to develop life. Each star has its own habitable area that is determined by the type and amount of energy released.
The L 98-59 star system is gradually attracted to astronomy. Each confirmed planet is equally attractive and everyone is in the habitable band. The planet is close to the star of Venus, but 85 % is Earth. The second is approximately 2.5 times the huge of our planet. The third may be 30 % oceanic. There is little known about the fourth case, except that this is a “super earth”-a mentor used to describe planets larger than ourselves, but smaller than the ice giants in our solar system.
Currently, there is no picture of the L 98-59 F. The next step will be to use advanced James Web Space Telescope technology to try to get a direct image.
In a statement issued by the University of Montreal, “These results confirm L-98-59 as one of the most convincing systems surrounding the diversity of stone planets and ultimately, search for life signs.”
There is only another well-known star system in the complexity and number of planets: TRAPPIS-1, 39 light-years away from Earth. It is a Ultracool dwarf star with at least seven rocky planets, three of which are in the area.
