China has proposed a special space exploration that will focus on finding a habitable exoplanet. The mission will involve releasing a spacecraft responsible for scanning the wobbling stars.
The Closeby Habitable Exoplanet Survey or CHES will rely on the micro-arcsecond relative astrometry, which is centered on delivering ultraprecise measurements for the movement of the stars.

The newly-proposed Chinese mission will be focused on searching for habitable exoplanets across the galaxy.
Space agencies all over the world are now set to hunt a potential foreign planet that could house the living species. According to Space.com, China is the latest nation to plan to launch an exoplanet mission anew.
The astronomers will use CHES to detect various exoplanets in space. They would also determine the distance of these planetary bodies from the orbiting stars.
The European Space Agency (ESA) and the National Aeronautics Space Administration (NASA) are using a similar technique that China is doing right now.
To be specific, ESA utilizes the Gaia space telescope, which is capable of building a 3D mapping of the stars existing across the Milky Way.
Meanwhile, NASA relies on the Transiting Exoplanet Survey Satellite, better known as the transit method. This is quite different compared because it focuses on detecting the star's luminosity.
The closest method to CHES is the Gaia. China wants to target hunting down exoplanets around the stars. It should be noted that the Earth-like planets could be 33 light-years away from the Earth.
"The hunt for habitable worlds about nearby sun-like stars will be a great breakthrough for humanity, and will also help humans visit those Earth twins and expand our living space in the future," CHES principal investigator Ji Jianghui said in an interview with Space.com.

Over 5,000 Exoplanets Discovered and Counting
At the moment, astronomers have already uncovered more than 5,000 foreign planets in existence. Out of those numbers, only 50 of them are considered to be suited for living.
Space.com added in the same report that CHES would start its mission approximately 930,000 miles away from the planet. This exact point is where the James Webb Space Telescope is currently situated.
According to Japan Aerospace Exploration Agency associate professor Elizabeth Tasker, the measure of the masses of the exoplanets orbiting the F and G stars will be an important addition to their data. This would also pave the way to find the habitable worlds out there.
Speaking of this mission, another China-led proposal appears to be competing with CHES. It should be noted that the Earth 2.0 mission will be implemented to monitor millions of stars. This idea will contribute to the exoplanet-seeking mission.
In another report from Phys.org, experts are preparing to train the high-precision spectrographs of the James Webb Telescope on its upcoming trip to the rocky exoplanets.
