NASA says a new “super-Earth” has been discovered in another solar system

NASA says a new “super-Earth” has been discovered in the “fairly nearby” solar system.

The exoplanet is “about one and a half times the width of Earth” and is located in a system just 137 light-years from Earth

A new “super-Earth” has been discovered in the habitable zone of the nearby solar system, according to NASA. The planet, called TOI-715 b, is “about one and a half times the width of Earth” and is located in a system that is only 137 light-years from Earth. NASA explains that this is “fairly close to us” – for comparison, our Milky Way Galaxy is about 100,000 light-years across. The planet orbits a red dwarf star, which is cooler and smaller than our sun. Because the star is cold, this super-Earth can orbit closer and remain within the solar system’s habitable zone, which is “the distance from the star that could give the planet the right temperature for liquid water to form on its surface.” Thus preserving life. Another side effect of the closest orbit is that the planet passes in front of its star more often, making it easier to track and observe — which is very easy, in this case, from “a year ago” on TOI-715. B lasts 19 days. Also in the same system is another, more Earth-like planet, which, if confirmed, “would become the smallest planet in the habitable zone ever discovered” by NASA’s Transiting Exoplanet Survey Satellite, or TESS for short, which was launched in 2018. TESS specifies Potential exoplanets, which are then visually confirmed and identified by NASA’s James Webb Space Telescope. This discovery was led by Georgina Dranfield and a team of scientists at the University of Birmingham, UK, and their findings were published in the journal. “Monthly Notices of the Royal Astronomical Society.” For a useful visual comparison between Earth and TOI-715 b, see NASA’s tool here. Super-Earths are classified as “more massive than Earth but lighter than ice giants such as Neptune and Uranus.” It can be made of gas, rock, or a combination of both. It is twice the size of Earth and up to 10 times its mass, according to NASA. Although this does not always mean that they are similar to our planet, which means that they are not always considered habitable. NASA explains that “planetary compositions may be 10 times larger than Earth,” and “there may be a wide range of planetary compositions, including water worlds, snowball planets, or planets, such as Neptune, that are largely composed of Dense gas.
