TOI-5628 A is 359 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M3.0±1.0 star; the first was found in 2026 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-5628 A b goes round its star every 4.34 days, 20 times as often as Mercury goes round the Sun.
TOI-5628 A is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

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.
