How does the size of Kepler-20e compare to Earth?
Answer
It is smaller than Earth
Kepler-20e holds significance in the study of exoplanets because it was identified as one of the smallest exoplanets confirmed to be rocky by the Kepler mission up to that point in time. While many Super-Earths were discovered, Kepler-20e was found to be smaller in physical size, or radius, compared to Earth itself. This fact underscores the technological capability required for the Kepler telescope, as detecting such a small world orbiting a distant star required incredibly precise measurements of the resulting dip in starlight.
