NASA’s Tess Mission found Six planet system perfectly tuned
NASA’s Tess Mission found Six planet system perfectly tuned Tracing a link between two neighbour planet at regular time interval along their orbits, creates a pattern unique to each couple. The six planets of the HD110067 system create together a mesmerising geometric pattern due to their resonance-chain. Credit: Thibaut Roger/NCCR PlanetS, CC BY-NC-SA 4.0 The planetary trove within the HD 110067 system presents a unique opportunity to explore the enigmatic class of "mini-Neptunes," absent in our Solar System. These planets, orbiting an orange star 100 light-years away, were initially discovered by NASA's TESS mission. Two inner planets, b and c, exhibited a resonant orbital relationship with periods in a 2:3 ratio. Upon detecting unattributed transits and considering the resonant orbits of b and c, researchers speculated the presence of a third planet, d, in a 2:3 orbital resonance with planet c. Utilizing this hypothesis, they successfully predicted and conf...
