TOI-1136 b is a super Earth exoplanet that orbits a G-type star. Its mass is 4.27 Earths and it takes 4.2 days to complete one orbit of its star. Its discovery was announced in 2022.

The six known planets orbiting a star very like the Sun are locked in orbital resonance, making for a well-timed planetary dance. The period ratios are near 3:2, 2:1, 3:2, 7:5, and 3:2, meaning that for every three orbits of the first planet, b, the second planet orbits twice, and so on.

The well-aligned planetary system and the lack of detected binary star companion together suggest that TOI-1136's resonant chain formed in an isolated, planetary disk with no stellar fly-by, disk warp, or significant axial asymmetry.
