TOI-700 e
TOI-700 e is the second outermost exoplanet orbiting TOI-700, a red dwarf star in the constellation of Dorado. Host star

TOI-700 is a red dwarf of spectral class M that is about 40% the mass and radius, and very roughly 50% of the temperature of the Sun. The star is bright with low levels of stellar activity. Over the 11 sectors observed with TESS, the star does not show a single white-light flare. The low rotation rate is also an indicator of low stellar activity. Orbit 
TOI-700 e orbits its host star with an orbital period of 27.8 days, comparable with the Moon's orbital period of 27.5 Earth days. It has an orbital radius of about , less than half of that of Mercury to the Sun in the Solar System. It receives about 130% of Earth's sunlight from its host star. Near orbital resonances 
TOI-700 e is in a near orbital resonance with TOI-700 c and TOI-700 d. It is in a near 5:7 resonance with TOI-700 c and a near 3:4 resonance with TOI-700 d.

Discovery 
In November 2021, a fourth possible planet, Earth-sized and receiving approximately 30% more flux from TOI-700 than Earth does from the Sun, was found at the inner edge of the habitable zone of TOI-700. In January 2023 the existence of this planet, designated TOI-700 e, was confirmed. Discovered in 2023, TOI-700 e is terrestrial exoplanet that NASA claims to be an "earth-like" planet, with 95 percent of the Earth’s radius. Discovered by NASA's TESS (Transiting Exoplanet Survey Satellite), TOI-700 e has mass of about 0.818 Earths and takes 27.8 days to orbit once around its star. The planet is in a habitable zone distance from the M-type star TOI-700 it orbits, leading NASA scientists to believe that there is potential for liquid water on its surface. Ten percent smaller than its neighboring planet TOI-700 d, both are at a distance from their sun to be considered habitable, however, TESS requires an additional year to acquire more data about the exoplanets. Being one in only about a dozen habitable zone planets known, further research and data collection of the TOI-700 solar system is important for understanding Earth-like planets. References
