A distant exoplanet mysteriously vanished from sight. Astronomers just discovered why

After extensive observation spanning seven years, astronomers have identified the cause behind the sudden disappearance of the exoplanet TOI 700 e. The planet was initially detected in 2018 and subsequently observed as part of NASA’s Transiting Exoplanets Survey Satellite (TESS) mission. Researchers utilized data from TESS to determine that the planet's orbit shifted significantly over time due to gravitational interactions with its host star, TOI 700. This orbital change caused the planet to move out of view as it moved further away from Earth’s line of sight. Scientists now understand this phenomenon is a common occurrence among exoplanets orbiting distant stars.
