NASA Space Technology Using NASA's exoplanet-hunting spacecraft, the Transiting Exoplanet Survey Satellite (TESS), scientists have spotted a record-breaking triple-star system so tightly bound that it could fit comfortably between the sun and its closest planet, Mercury.The system, designated TIC 290061484 contains twin stars that race around each other once every 1.8 Earth days as well as a third star that orbits this pair once every 25 Earth days. This triple star system's super-tight orbit, located just under 5,000 light-years away in the constellation Cygnus, the swan, makes it a record-breaker.The previous record-holder for the tightest three-star system orbit is Lamba Tauri, which set the record in 1956 with its third star taking 33 days to orbit its inner twin stars.Related: Giant exoplanet the size of 2 Jupiters has a hidden companion disturbing its orbitThe discovery...
