TOI-700 e is the second outermost

red dwarf star in the constellation of Dorado
.

Host star

Main article: TOI-700

TOI-700 is a

spectral class M that is about 40% the mass and radius, and very roughly 50% of the temperature of the Sun.[1] 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.[2]

Orbit

TOI-700 e orbits its host star with an orbital period of 27.8 days, comparable with

sunlight from its host star.[citation needed
]

Near orbital resonances

TOI-700 e is in a near

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.[citation needed

Exoplanet

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.[3] In January 2023 the existence of this planet, designated TOI-700 e, was confirmed.[4]

Discovered in 2023, TOI-700 e is terrestrial exoplanet that NASA claims to be an "

TESS requires an additional year to acquire more data about the exoplanets.[6] 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.[7]
