A proposed Chinese mission
would look for nearby potentially habitable alien worlds by launching a spacecraft for scaning wobbling stars
For this mission, called the
Closeby Habitable Exoplanet Survey (CHES), the scientists would use a method called micro-arcsecond relative astrometry.
This technique involves
taking ultraprecise measurements of the positions and movements of stars compared with a background reference stars
This technique will detect
the perturbations of a star resulting from the gravitational influence of exoplanets as they orbit their stars.
CHES would be much
more focused than Gaia, targeting 100 sun-like stars within 10 parsecs, or 33 light-years,
IT would be able to
detect potentially Earth-like planets in the habitable zones around those stars.
