SixPlanet

An international team of astronomers used the CHEOPS and TESS satellites to discover a system of six planets orbiting the star HD110067 in a unique harmonic resonance. This rare finding, involving a chain of 3:2 and 4:3 resonances, was initially challenging to decipher but was eventually solved, revealing the precise orbital periods of the planets. An international collaboration between astronomers using the CHEOPS and TESS space satellites, including NCCR PlanetS members from the University of Bern and the University of…

Scientists have discovered a unique star system, HD110067, where six planets orbit in a rhythmic gravitational lockstep, a rare phenomenon that could reveal new insights into planet formation and evolution. Study led by University of Chicago astronomer Rafael Luque may tell us about how planets form. Scientists have discovered a rare sight in a nearby star system: Six planets orbiting their central star in a rhythmic beat. The planets move in an orbital waltz that repeats itself so precisely it can be readily set to…

Astronomers have discovered an uncommon star system located just 100 light-years away from us, with six planets huddled immensely close to their host star — so close, in fact, that all their orbits could fit within the distance between Mercury and our sun. Puzzlingly, unlike our own solar system, it appears this newfound slice of the cosmos has remained largely unchanged since its birth over a billion years ago."If the galaxy was the Empire State Building, we can only see and detect the planets next to stars that have…
