Half the size of Venus: Weighing the smallest exoplanet yet
From Ars Technica:
"Most of the exoplanets we've discovered have been identified by large surveys like the Kepler mission or the Transiting Exoplanet Survey Satellite (TESS). While these projects are great at spotting stars that host planets, they mostly just tell us that the planets are there. Understanding an exosolar system and its planets requires multiple follow-up observations—and the telescope time that goes with them. Here, the phenomenal success of the surveys has given us far more to observe than we can get to conveniently."

Re: Half the size of Venus: Weighing the smallest exoplanet yet
With so much data coming in, this has to be an exciting area to work in.
Any metaphor will tear if stretched over too much reality.
