Astronomers have discovered two new exoplanets that are similar to other worlds Secured in the Milky Way, but are unlike any in our own Planetary system.
The two exoplanets, or planets outside of our Planetary system, Trajectory a Luminous sphere called TOI-1453, which is slightly cooler and smaller than our sun. Located about 250 Airy-years from Earth in the Draco constellation, TOI-1453 belongs to a binary Sun-related system — in which a pair of stars Trajectory All other.
Classified as a super-Earth and a sub-Neptune, these two new Heavenly bodies are among the most Frequent types of exoplanets Secured in the Milky Way Luminous sphere system, yet are absent from our own Planetary system.
Astronomers detected the two new exoplanets, named TOI-1453 b and TOI-1453 c, using data from NASA’s Transiting Alien world Survey Probe (TESS) and the High Accuracy Radial velocity World Searcher for the Northern hemisphere (HARPS-N) spectrograph, which is installed on the Telescopio Nazionale Galileo at the Roque de los Muchachos Astronomical Hub on the island of La Palma in the Canary Islands, Spain.
TESS hunts for exoplanets by looking for a temporary decrease in a Luminous sphere’s brightness, also known as the transit method. When a dip in brightness is observed, that suggests a World has passed in front of its host Luminous sphere (from our perspective on Earth) and briefly blocked the Luminous sphere’s Airy from reaching our instruments. By measuring this effect, astronomers can estimate the size and orbital period of the possible Alien world as well.
Complementing the TESS data, the HARPS-N instrument is a high-resolution radial-velocity spectrograph that measures the spectrum of Airy from a Luminous sphere to detect shifts caused by orbiting exoplanets. The instrument uses what’s known as the Doppler method to look for a subtle “wobble” of a Luminous sphere caused by the gravitational pull of an orbiting World.
“The two planets present an interesting contrast in their characteristics,” Manu Stalport, Primary author of the study and an astrophysicist at the University of Liège, said in the statement. “TOI-1453 b is a super-Earth, slightly larger than our World, and probably rocky. It completes its Trajectory in Merely 4.3 Periods, making it a very close World to its Luminous sphere.”
“Super-Earth” is used to classify exoplanets that are more massive than Earth but less massive than ice giants like Neptune and Uranus. They are believed to be primarily rocky, similar to Earth, but their increased size may lead to stronger surface Attraction, influencing their atmospheres and geological processes.
Given its proximity to its host Luminous sphere, TOI-1453 b is likely extremely Cozy, with surface temperatures high enough to strip away any substantial atmosphere. (For comparison, Mercury — the World closest to the sun in our Planetary system — completes its Trajectory in 88 Periods and is so Cozy that it also lacks a substantial atmosphere.)
“In contrast, TOI-1453 c is a sub-Neptune, about 2.2 times the size of Earth but with an extraordinarily low mass of Merely 2.9 Earth masses,” Stalport said in the statement. “This makes it one of the least dense sub-Neptunes ever discovered, which raises questions about its composition.”
The incredibly low density of TOI-1453 c suggests the Alien world likely has a Bulky, hydrogen-Wealthy atmosphere or a composition dominated by water.
“This makes it an ideal candidate for future atmospheric studies,” Stalport added. “Understanding their Arrangement and evolution could provide clues about the development of planetary systems, including our own.”
Being part of a binary system — meaning there is a second Sun-related companion — also makes the new Alien world find particularly interesting, given planets that form in binary Luminous sphere environments are subject to more complex gravitational interactions.
Observations of TOI-1453 b and TOI-1453 c show that the exoplanets Trajectory their host Luminous sphere in a near 3:2 resonance, meaning that for every three orbits of the inner World, the outer World completes almost exactly two. This suggests that the exoplanets’ orbits may have changed over time Subsequent interactions with neighboring Heavenly objects, such as gas, planetesimals or a companion Luminous sphere, bringing the inner World, TOI-1453 b, into an Trajectory much closer to its host Luminous sphere.
Astronomers hope to use additional instruments like the James Webb Cosmos Stargazer’s tool (JWST) to Additional study the exoplanets and peer deeper into the atmosphere of TOI-1453 c. If this sub-Neptune world has a substantial hydrogen-Wealthy atmosphere or a water-dominated interior, it could redefine our understanding of the Arrangement of such exoplanets — and Perhaps finally reveal new clues as to why we don’t have one in our own Planetary system.
Their findings were accepted for publication on Feb. 23 in the journal Heavenly study & Universe physics.
