The average life expectancy on the newly discovered potentially habitable planet, which is 100 light years from Earth, would be 3,158 years. A multidisciplinary team of researchers, under the direction of astrophysicist Laetitia Delrez, have discovered two planets orbiting the star TOI-4306. The observations allowed for the detection of a second, previously undiscovered planet in addition to helping to confirm the first one.
About 6.5 times smaller and half as hot as our sun is TOI-4306. The first planet is designated as TOI-4306b or LP 890-9b. It is only 2.7 days to complete an orbit around its star and is about 40% larger than the Earth. The average lifespan on Earth right now is 73.5 years. As a result, TOI-4306b, which has a much shorter year due to its extremely brief orbit, would have an average life expectancy of 9,943 years.
According to NASA, super-Earths are a special class of exoplanets in the solar system that are larger than our planet but lighter than the ice giants. They can grow up to ten times the mass of the Earth and are created from a mixture of gas and rock.The research will be published in the journal Astronomy and Astrophysics and was made possible by NASA’s Transiting Exoplanet Survey Satellite and the Search for Habitable Planets Eclipsing Ultra-Cool Stars (SPECULOOS) project at the University of Liège.
The nearly 1,600 known super-Earths are larger than Earth but lighter than icy planets like Uranus and Neptune, unlike any other planets in our solar system. Exoplanets, or planets found outside of our solar system, are typically either extremely hot or extremely cold, making them uninhabitable. Last year, researchers found TOI-1431b, a “hellish world” with an average daily temperature of 2,700 degrees Celsius. Undoubtedly not a place where people could live.
The University of Liège’s researchers confirmed and characterised this planet using their ground-based SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) telescopes, and they also thoroughly explored the system in search of additional planets that TESS might have “missed.”
