Detailed explanation-1: -Its discovery was announced on 27 June 2019 on the NASA website. It was the smallest planet discovered by TESS until the discovery of LHS 1678b, and was the lowest-mass planet whose mass has been measured using radial velocities until Proxima Centauri d was found in 2022.

Detailed explanation-2: -Astronomers discovered the latest planet in 2022, named HD 109833 b, it is a Neptune-like exoplanet that orbits around a G-type star. The astronomers found it using the transit method.

Detailed explanation-3: -In 2020, Gilbert and others announced the discovery of the Earth-size, habitable-zone planet d, which is on a 37-day orbit, along with two other worlds. The innermost planet, TOI 700 b, is about 90% Earth’s size and orbits the star every 10 days.

Detailed explanation-4: -L 98-59 b is a terrestrial exoplanet that orbits an M-type star. Its mass is 0.4 Earths, it takes 2.3 days to complete one orbit of its star, and is 0.02191 AU from its star. Its discovery was announced in 2019.

Detailed explanation-5: -NASA has discovered an Earth-sized planet orbiting in the habitable zone of its star. Scientists have discovered a world that is likely rocky and 95% of the size of Earth. The planet, called TOI 700 e, is orbiting around a star and could have liquid water on it, NASA says.
