LTT9779b semi-major axis = 0.01679 au as previously stated in post #3. There are a bunch of exoplanets now documented with orbits as close or closer than Venus in our solar system, some 49% or more of the data. Most of those exoplanets are large radii size and masses. The exoplanet.eu site currently shows 5460 confirmed, the NASA archive site shows 5470 confirmed. Using the exoplanet.eu site, 2683 orbit closer than Venus in our solar system (a <= 0.73 au), mean mass 2.48 Jupiter masses. The NASA site shows 2693 and mean mass 1.19 Jupiter masses. Radii compared to Earth quite large too, mean near 5.9 earth radii for both list of exoplanets (indicating many exoplanets will have higher surface gravity well and larger escape velocities than Earth). Our solar system arrangement is very different. CHEOPs is finding exoplanets that are large and closer to their parent stars, TESS too. TESS shows 363 confirmed, semimajor axis range 0.00622 au to 0.9 au, mean mass 262.9 earth masses. What do observations like this indicate when looking for ET phoning home or other exoplanets that are claimed to be earthlike with possible life on them or in the habitable zone? IMO, astrobiology and claims of ET phoning home in the Milky Way, have a long way to go to be science.
