Fourth planetary system with nodal precession identified. TOI 1518 b grazes the disk of its parent star

Star system: TOI-1518 | Distance from the Sun: 742 light years

The planets orbit is not perfectly aligned with the stars equator, but tilted at a sharp angle. This tilt, combined with the stars rapid rotation, causes the planets trajectory to slowly wobble over time, a phenomenon called nodal precession.
