24 Sextantis, also known as HD 90043, is a single K0IV subgiant star about 235 light-years away in the constellation Sextans. Two giant planets with minimum masses of approximately 1.99 and 0.86 times that of Jupiter were discovered via the radial velocity method in 2010, with orbital periods of 452.1 days and 883 days, respectively. The planets are in a 2:1 resonance, but the system was found to be dynamically unstable in 2019.
