December 17th of 2019 is The Launch Date of The CHEOPS_Mission to measure The Radii of EXOPLANETS Which have already been discovered by now.
This is The Smallest Sized EXOPLANET Discovered by NASA's TRANSITING EXOPLANET SURVEY SATELLITE so far!
NASA's TESS mission finds its smallest planet yet
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star. The planet, called L 98-59b, marks the tiniest discovered by TESS to date.
Two other worlds orbit the same star. While all three planets’ sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets – that is, planets beyond our solar system – that have the best potential for this kind of follow-up.
“The discovery is a great engineering and scientific accomplishment for TESS,” said Veselin Kostov, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the SETI Institute in Mountain View, California. “For atmospheric studies of small planets, you need short orbits around bright stars, but such planets are difficult to detect. This system has the potential for fascinating future studies.”
A paper on the findings, led by Kostov, was published in the June 27 issue of The Astronomical Journal.

A Huge_Planet that’s "too big for its Host_Star" has been spotted orbiting a Faint Red_Dwarf Star by some Australian Researchers - with the help of a Backyard Astronomer.
Three planets with sizes and temperatures akin to those of the Earth and Venus are circling a dwarf star 40 light-years away. The star in question, named TRAPPIST-1 after the telescope used to observe it, is weaker and cooler than the Sun at the heart of our solar system. "With such short orbital
