by K2-290A, the primary star in the triple stellar system K2-290, is tilted by 124 degrees compared with the orbits of both of its known planets, and has a wide-orbiting companion that is capable of having tilted the protoplanetary disk.
K2-290, also known as BD-19 4173 and TIC 70803960, is a triple system located 897 light-years away in the constellation of Libra.
In 2019, two transiting planets were discovered around the primary star in the K2-290 system.
The inner planet, K2-290Ab, has an orbital period of 9.2 days and a radius of 3 Earth radii, making it a hot sub-Neptune.
The outer planet, K2-290Ac, is a warm Jupiter with orbital period 48.4 days and a radius of 11.3 Earth radii.
