TOI-169 and Its Jupiter-Like Planet
TOI-169 is a Sun-like G-type dwarf star 1330 light-years away, with a reported age of 4.7 billion years. Its mass is 1.15 solar masses and its radius is 1.29 solar radii, both larger than the Sun's, and its reported temperature of 5880 K is hotter than the Sun's. One planet orbits this host.
That planet, TOI-169 b, is a Jupiter-like world discovered by transit in 2020. It completes an orbit every 2.26 days. Its radius is 12.2 Earth radii and its mass is 251 Earth masses, both larger than Earth's. Its mean density is 0.768 g/cm³, 0.139 times Earth's.
