I like the paper link reported in the article, https://iopscience.iop.org/article/10.3847/1538-3881/ab893e The abstract has some geeky, exoplanet details OGLE-2018-BLG-0677 is studied for sometime now and distance said to be 0.63 to 0.72 AU from the host star for 0677 b. This site shows 4266 confirmed exoplanets now, http://exoplanet.eu/ 120 exoplanets have been found using the microlensing method.
