Exoplanet ‘Super-Earth’ found revolving around one of the oldest stars in the Milky Way

The universe is a deep mystery, and astronomers and other experts are constantly trying to unravel one or the other mystery through their research. In a recent study, it has been discovered that a hot and rocky exoplanet exists which is known as super-Earth. The planet is present in the Milky Way galaxy and is believed to orbit one of the oldest stars in the galaxy.

According to a report published in CnnSuper-Earth is being called exoplanet because it lies outside the solar system. The reason behind the name is that the super-Earth has three times the mass of the Earth and is about 50% larger than the Earth. This planet is also known as TOI-561b.

According to experts, Super-Earth can complete a revolution around its star in less than half of Earth Day. As far as the temperature of this planet is concerned, it is 3140+ degrees Fahrenheit somewhere. The surface temperature is the result of proximity to the star. Stephen Kane, study co-author and astrophysicist at the University of California, Riverside, confirmed the information about class time in a statement. He mentioned that every day a person spends on Earth, the exoplanet revolves around its star twice.

The next obvious question that arises here was how this planet named TOI-561b was discovered. Experts found the planet through a Transiting Exoplanet Survey Satellite (TESS) mission that was launched in 2018 by the National Aeronautics and Space Administration (NASA). The said planet was found in the thick galactic disk of the Milky Galaxy. To be absolutely certain of his discovery, experts went to the WM KK Observatory in Hawaii to determine the mass, radius, and density of super-Earths. An understanding of mass and radius helps astronomers learn more about its internal structure.

His findings were shocking because he found that even though the planet’s mass is three times that of Earth, its density is nearly the same. Stephen Kane reacted to this by saying, “It’s surprising because one would expect higher densities.”

He also mentioned that this planet is not capable of supporting habitable life. Stephen said that knowing about the interior of the planet helps in understanding whether the planet’s surface is habitable or not. While this particular planet is unlikely to exist today, it may yet be a precursor to many rocky worlds to be discovered around the oldest stars in our galaxy.
