The radius of the earth and the radius of orbit around the sun are 6371 km and 149 xx 10^(6) km respectively. The order of magnitude of the diameter of the orbit is greater than that of earth by

A planet is revolving around the sun as shown in the figure. The radius vectors joining the sum and the planet at points A and B are 90 times 10^6 km and 60 times 10^6 km , respectively. The ratio of velocities of the planet at the points A and B when its velocities makes angle 30^@ and 60^@ with major axis of the orbit is

(a) Estimate the average orbital speed of the earth going around the sun. The average Earth-sun distance is 1.5xx10^(11)m. (b) An asteroid going around the sun has an average orbital speed of 15 km/s. Is the asteroid farther from the sun or closer to the sun as compared to the Earth? Explain your answer.

A planet is revolving around the sun as shown in the figure. The radius vectors joining the sun and the planet al points A and B are 90 xx 10^6 km and 60 xx 10^6 km respectively. The ratio of velocities of the planet at A and B when its velocities make 30^@ and 60^2 with major axis of the orbit is

The mean orbital radius of the Earth around the Sun is 1.5 xx 10^8 km . Estimate the mass of the Sun.
