HIP 8152

Planetary system · 331.7 light-years away · also HIP 8152

HIP 8152 is 332 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,618 K star; the first was found in 2023 by transit (Transiting Exoplanet Survey Satellite (TESS)).

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.

The planets, compared

For a star of 5,618 K, 0.83 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.87 to 1.55 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.

The light you see left 332 years ago, around 1690.
