Apparent magnitude is used to describe...
any two masses attract each other with a force equal to a constant (constant of gravitation) multiplied by the product of the
hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas.
that other galaxies exist beyond the Milky Way
observing the location of a star at different times of the year as Earth orbits
electromagnetic radiation
