An Earth-like exoplanet is expected to be 35 light-years away. In the same system is the lightest known exoplanet.
The basics in brief
- Astronomers have discovered the lightest exoplanet with the help of the “Espresso” instrument.
- An Earth-like planet is believed to be in the same solar system.
- The “Espresso” tool allows you to find out the density of a planet.
A team of astronomers has discovered a star 35 light-years away, around it Lightest known exoplanet circles. An Earth-like planet is also suspected in the system.
“We have evidence of a terrestrial planet in the habitable zone of this system.” So, Olivier Demangon, researcher at the Instituto de Astrofísica e Ciências do Espaço at the University of Porto and lead author of the new book study. This is an important step in the search for life on Earth-sized planets outside the solar system.
Espresso tool provides new knowledge
In addition, a planet half the mass of Venus was discovered. with help from «Espresso» – Tools At the European Southern Observatory’s Very Large Telescope (ESO VLT) in Chile. This writes the University of Geneva In a letter from Thursday. It is the “lightest” exoplanet measured using the radial velocity technique.
A planet has also been identified that is definitely more oceanic nature Plus one in the habitable zone. the NASAThe TESS satellite identified the three planets on their way around the star L 98-59. Its size ranges from 0.85 to 1.52 times the size of a land specific.
The espresso tool has now determined its intensity Conclusions about the water content Planet allows. The research team was able to conclude that the two planets are likely to be dry, but in small quantities Water It contains. The mass of the third planet can reach 30% Water exist, making it an oceanic planet.
An Earth-like exoplanet in a habitable zone
In addition, the team discovered a fourth planet and suspected a fifth. This in the region is the correct distance from the star to Water to be on its surface. Therefore, it could be an Earth-like exoplanet with Earth-like proportions.
