1) It is discovered using the gravitational microlensing technique. The new finding states that the size and orbit of this planet are comparable to that of Earth.

A Super-Earth is an extrasolar planet with a mass between 1 and 10 times that of Earth but substantially below those of the Solar System’s ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth’s, respectively The potentially rocky planet, known as Barnard’s star b, is a ‘super-Earth’ and orbits around its host star once every 233 days, said researchers from Queen Mary University of London. K2-18B is classified as a super-earth because it is bigger than our earth twice as big in fact as well as eight times heavier. Researchers have found a new “one in a million” Super-Earth planet towards the genre of the galaxy. All of them are categorised as super-Earths, that is, with masses that are larger than Earth’s but less than Neptune’s.The star named GJ9827 is one of the few known stars to have multiple transiting terrestrial-sized exoplanets that are suited for atmospheric characterisation. 3) The planet is expected to have a mass between the Earth’s mass and that of Neptune. Context: Researchers have discovered a new exotic planet outside our solar system in the constellation Cassiopeia. About: The super-Earth planet -- named GJ 357 d -- was discovered in early 2019 owing to NASA's Transiting Exoplanet Survey Satellite (TESS), a mission designed to comb the heavens for exoplanets. The exoplanet orbits a red dwarf star, K2-18 and is 110 light-years away from Earth in the Leo constellation. A new ‘Super-Earth’ planet orbiting Proxima Centauri, which is the Sun’s nearest neighbouring star, has been discovered by scientists, who published the results in the journal Science Advances. a) Only 2 and 3 b) Only 1 and 2 Astronomers have discovered a frozen planet with a mass over three times that of the Earth, orbiting the closest solitary star to the Sun. Its three exoplanets are particularly interesting because two of them have radii between 1.5 and 2.0 Earth-radii. According to the study, water vapour has been detected on a potentially habitable super-earth known as K2-18B located about 110 light-years away in the constellation Leo. Scientists have discovered a new ‘super Earth’ type exoplanet named as GJ 536b orbiting a very bright star near to our Sun. According to researchers from Queen Mary University of London, the potentially rocky planet, known as Barnard’s star b, is a ‘super-Earth’ and orbits around its host star once every 233 days. 9) Which of the following statement(s) is/are correct about Super Earth Planet. Super-Earths are exoplanets that are larger than Earth but smaller than Neptune. For Prelims and Mains: About Super- Earth and Constellation Cassiopeia.
