What determines the size of a planet?
The distance to a planet enables us to determine its size, through its angular diameter. Doppler Spectroscopy. – This one can involve measuring the “wobbling” of stars in order to measure the planet’s diameter. In this method, results can vary by our perception of the number of planets in the system.
What is the relative size of the planet Earth?
