A saturn year is 29.5 times the earth year. How far is the saturn from the sun if the earth is `1.50 xx 10^8 km` away from the sun ?

How far is the sun from the earth?

How does the heat energy from the sun reaches earth?

A rocket is fired vertically with a speed of 5 km s^-1 from the earth’s surface. How far from the earth does the rocket go before returning to the earth ? Mass of the earth = 6.0 xx 10^24 kg , mean radius of the earth = 6.4 xx 10^6 m , G = 6.67 xx 10^-11 N m^2kg^-2 .

If the earth be one-half its present distance from the sun, how many days will be in one year?

Calculate the force of gravitation between the earth and the sun, given the mass of earth = 6xx 10^24 kg and of the sun = 2 xx10^30 kg . Average distance between the two is 1.5xx 10^10m .
