Gl 725 B is 22.3 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M4 star; the first was found in 2026 by radial velocity (Mauna Kea Observatory).
Fly there in 3DGl 725 B c goes round its star every 37.9 days, 2.3 times as often as Mercury goes round the Sun.
Gl 725 B is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

Gl 725 A is a M3V star of magnitude 9.11, with a computed orbit. In 2025 it was 10.9″ from Gl 725 B, at position angle 5° (Washington Double Star Catalog, 18428+5938 STF2398 AB): 74.6 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |

| Gl 725 B c | 37.9 days | 0.139 AU | 1.66 R⊕ estimated | 3.4 M⊕ minimum | Radial Velocity, 2026 |
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.
