How Ancient Indians knew Sun to Earth Distance?

The Sun and Earth each exert a gravitational force on the Moon. What is the ratio F_("sun")//F_("Earth") of these two forces? (The average Sun-Moon distance is equal to the Sun Earth distance.)

The moon revolves round the earth 13 times in one year. If the ratio of sun-earth distance to earth-moon distance is 392 , then the ratio of masses of sun and earth will be

How far from earth must a body be along a line towards the sun so that the sun's gravitational pull on it balances that of the earth . Distance between sun and earth's centre is 1.5 xx 10^(10) km . Mass of the sun is 3.24 xx 10^(5) times mass of the earth .

How far from Earth must a body be along a line joining the sun to the earth so that resultage gravitational pull on the body due to Earth and sun is zero ? Distance between sun and the Earth is 1.5 xx 10^(8) km . Mass of sun = 3.25 xx 10^(5) times mass of Earth.

If r is the distance between the Earth and the Sun. Then, angular momentum of the Earth around the sun is proportional to

The distance of a planet from the sun is 5 times the distance between the earth and the sun. The time period of the planet is
