HD 60779

Planetary system · 115.6 light-years away · also HD 60779, HIP 36976

HD 60779 is 116 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G1 V star; the first was found in 2026 by radial velocity (Roque de los Muchachos Observatory).

Worth knowing

HD 60779 b goes round its star every 30.0 days, 3 times as often as Mercury goes round the Sun.

Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

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 6,081 K, 1.6 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.17 to 2.04 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 116 years ago, around 1910.
