HATS-74 A is 976 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 3,777 K star; the first was found in 2021 by transit (HATSouth).
Fly there in 3DHATS-74 A b goes round its star every 41.6 hours, 51 times as often as Mercury goes round the Sun.
HATS-74 A is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HATS-74 A A has no spectral type listed of magnitude 19.2, moving through space with it. In 2020 it was 0.8″ from HATS-74 A, at position angle 228° (Washington Double Star Catalog, 11241-1933 TOI 737): 240 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HATS-74 A b | 41.6 hours | 0.0238 AU | 11.568 R⊕ | 464.03 M⊕ | Transit, 2021 |
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.
