Discovery of two similar exoplanets in near resonance around star TOI 4342

Astronomers report discovery of two sub-neptune exoplanets orbiting red dwarf star TOI 4342 in near orbital resonance. Year on the inner planet lasts 5.5 days and on the outer planet almost twice as long. That means both bodies meet each other periodically once every year on the second planet.
