TOI-815 is 195 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this K3 V star; the first was found in 2024 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-815 b goes round its star every 11.2 days, 8 times as often as Mercury goes round the Sun.
TOI-815 is one of 2 stars in its system. The position of the other star is not catalogued, so only TOI-815 and its planets are drawn.

Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
