This star system includes five potentially habitable planets

Team of Astronomers at the University of Montreal have discovered something new that is potentially habitable exoplanet Rotate Red Dwarf Stars L 98-59, 35 light years from Earth. This discovery means that there are five confirmed planets in this solar system. “temperate” or “livable” zonean area of the solar system where liquid water may be present on the surface of a planet.

The newly discovered planet, known as “L 98-59 F,” was able to avoid previous observations as it did not pass between Earth and the star during orbit, known as “transit.” Planets passing through the host star are easy to find as the mini-Ecripps you create as they pass through the star’s surface can be seen through the telescope.

the study Announce the discovery of the planet. This is waiting for publication Astronomy Journal– Reduced planets through subtle variations in the host star’s movements. The turbit star exerts gravity on the host as it moves the star slightly into orbit. These movements can reveal the existence of planets even if they are not visible.

The obvious movement of the L 98-59 was picked up by two instruments specially designed for planet hunting: high precision Harps SpectrographIt was installed on the European Southern Observatory (ESO) telescope, Espresso Rocky Explanet Spectrographpart of the very large telescope (VLT) of ESO’s Delusional Observatory in Chile.

L 98-59 F stands out from other planets in the solar system because it receives a similar amount of solar energy to Earth. According to Montreal researchers, if it has the right atmosphere, it could be a temperate planet that can hold liquid water on its surface.

In addition to allowing the presence of liquid water, habitable zones of the solar system are areas where potentially planetary states can allow for the development of life. Each star has its own habitable zone, determined by its type and the amount of energy it emits.

The L 98-59 star system is gradually gaining attention among astronomy enthusiasts. Each confirmed exoplanet is just as intriguing as the others, and everything is in a habitable band. The planet closest to the star is half the mass of Venus, but 85% of the Earth’s size. The second is almost 2.5 times the size of our planet. The third is 30% ocean. Little is known about the fourth, but that too “Super Earth”– A term used to describe planets larger than ourselves but smaller than the ice giants of the solar system.

At the moment, there are no images of the L 98-59 f. The next step is James Webbspace Telescope It tries to capture a direct image of it.

“These results confirm that L 98-59 is one of the most compelling nearby systems to explore the diversity of rocky planets, and ultimately they are looking for signs of life,” says A. statement Published by the University of Montreal.

There is only one other known star system with similar numbers of exoplanets in complexity and number. This is 39 light years from Earth. This is a super cool dwarf star with at least seven rocky exoplanets, three of which are located in habitable areas.
