I understand how they measure mass, but how do they measure an exoplanet's radius, especially to that precision?

- dotancohen 1y agoI did not read this paper, but typically the diameter can be inferred by the transit time.
- teamonkey 1y agoNot sure in this specific case, but usually by measuring the brightness of the star as the planet passes in front of it, like a partial eclipse. That’s why most of the planets we have discovered are giants.
