NGTS-1 is an M-type star 711 light-years away, with a spectral type of M0.5, a small, cool red dwarf. Its mass is 0.617 solar masses, its radius is 0.573 solar radii, and its temperature is 3920 K. Each of these estimates is smaller or cooler than the Sun's corresponding value. One planet orbits this host.
That planet is NGTS-1 b, a Jupiter-like world discovered by transit in 2017. Its radius is 14.9 Earth radii, larger than Earth's, and its mass is 258 Earth masses, also larger than Earth's. Its mean density is 0.429 g/cm³, 0.0779 times Earth's. NGTS-1 b completes an orbit in 2.65 days.
