NASA's 'Transiting Exoplanet Survey Satellite' – Unveiling a Celestial Ballet
Astronomers, fueled by a paper in the journal Neptune, have unveiled a mesmerizing celestial ballet – a six-pack of planets orbiting HD110067. This dance, dating back at least 4 billion years, showcases the harmonious rhythm of these planets as they gracefully circle their nearby sun.
The Enigma of 'Sub-Neptunes'
Termed "sub-Neptunes" due to their size, these planets captivate astronomers with their uniqueness. As if choreographed by the cosmos, the star HD110067 boasts a planetary entourage that challenges our understanding of planetary systems.
TESS Chronicles: 2020's First Glimpse
The celestial dance first caught astronomers' attention in 2020 when NASA's TESS identified the initial pair of planets orbiting HD110067. This marked the beginning of a cosmic saga, with TESS serving as our cosmic guide through the uncharted territories of this distant solar system.
A Cosmic Collaboration: TESS and CHEOPS Unveiling Secrets
The exploration continued in 2022, with TESS joined by the European Space Agency's CHEOPS satellite. This collaborative effort, involving over 150 scientists from 12 countries, resulted in a comprehensive paper detailing the planetary system of HD110067.
HD110067: A Stellar Neighborhood
Situated in the northern constellation of Coma Berenices, HD110067, though invisible to the naked eye, holds significance in our cosmic neighborhood. Being only 100 light-years away, it stands as a suburb of the Milky Way, 10,000 times brighter than the red dwarf star TRAPPIST-1.
The 'Sub-Neptunes' Unveiled
HD110067, a star 20% smaller and cooler than the Sun, introduces us to a set of planets with temperatures soaring to 200 degrees. These 'sub-Neptunes' bridge the gap between rocky planets like Earth and Venus and the colossal ice giants Neptune and Uranus, boasting diameters two to three times that of Earth.
In Our Cosmic Backyard
Despite their extreme conditions, these planets are part of our cosmic neighborhood, offering a glimpse into the diversity of planetary systems within the Milky Way. Their proximity, a mere 100 light-years away, positions them as intriguing subjects for future astronomical studies.
