A recent study published in Nature reveals the identification of six exoplanets orbiting the bright star HD 110067 in the Coma Berenices constellation. Positioned between Earth and Neptune in size, these ‘sub-Neptunes’ offer insights into their composition, formation, and atmospheres. NASA’s TESS and the CHEOPS satellite facilitated observations, unveiling orbit details ranging from approximately nine to 54 days. The planets exhibit low densities, possibly attributed to expansive, hydrogen-rich atmospheres. Remarkably, the system’s resonant orbits imply stability since its formation over four billion years ago. HD 110067, notably the brightest star hosting more than four transiting exoplanets, presents a unique opportunity for understanding sub-Neptunes and their formation.
