Worth knowing

NGTS-14 A b goes round its star every 3.54 days, 25 times as often as Mercury goes round the Sun.

NGTS-14 A is one of 2 stars in its system. The position of the other star is not catalogued, so only NGTS-14 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.

The planets, compared

For a star of 5,187 K, 0.49 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.69 to 1.23 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 1,051 years ago, around AD 980.
