Star system, 740 light-years
TOI-849 and its one planet
TOI-849 b is an exoplanet 3.64 times Earth's width, 740 light-years away, orbiting closer to its star than the habitable zone we compute for it.
TOI-849 is a star of spectral type G, 740 light-years from us, with one known planet.

measured The period, and where the table says so the width and the mass, by the method named in each section.
computed Anything marked computed: the size of an orbit where Kepler's third law corrects the table, the temperature of a bare ball at that distance, the starlight received, and the habitable zone.

It was found as a small, regular dip in its star's light each time it crosses in front of it in 2020. Its orbit is closer to its star than the habitable zone computed for it. The Archive's own distance for it is 0.0155 au; the three papers behind its period, its star's mass and that distance do not agree with Kepler's third law, so the page uses the one the period and the star's mass give.
