I’m a bit late,but it needs to be posted as it is to important.
Now exoplanet community looks into a bright future. This year NGTS will have first light detecting new hot Neptunes and super-Earth planets. This will be followed by CHEOPS (ESA), a characterizing mission and TESS (NASA) which will detect hot/warm super-earth planets around nearby stars. And 2024 PLATO will go for an earth around another sun. And PLATO will allow to determine mass, radius and ages of planets with unprecedented precision.
This will not only give us the chance to have a second earth detected in my lifetime, but will give us a much more complete understanding on planetary systems, their formation and evolution. This might also change our view on the solar system.
