TOI-5688 A is 738 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 3,713 K star; the first was found in 2024 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-5688 A b goes round its star every 2.95 days, 30 times as often as Mercury goes round the Sun.
TOI-5688 A is one of 2 stars in its system. The position of the other star is not catalogued, so only TOI-5688 A 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.
