TIC 172900988 Aa is 819 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F9 star; the first was found in 2021 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTIC 172900988 b takes 200.5 days to go round its star once.
TIC 172900988 Aa is one of 2 stars in its system. The position of the other star is not catalogued, so only TIC 172900988 Aa 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.
For a star of 6,050 K, 4.7 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 2.02 to 3.55 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
