When determining the equator of a rotating planet, Boscovich's method requires how many surface feature observations?

  • Five

  • Three

  • Two

  • Four

Answer

The answer is three surface feature observations. Boscovich's method employs observations of three distinct surface features to precisely locate the equator of a rotating planet. By observing the positions of these features at different times of the day, scientists can determine the planet's rotational axis and subsequently, its equatorial plane. This method provides an accurate means to establish the planet's fundamental reference plane.
