is it true the size of the planet decides how much energy from the sun reaches the planet ,given a fixed orbit
Answers
Yes, it is true that the distances between the planets and the Sun are somewhat patterned. Venus is 1.8 times farther from the Sun than Mercury, and the Earth is 1.4 times farther from the Sun than Venus. Mars is 1.5 times the distance from Earth. This seems to be a pattern-every planet could be 1.4 to 1.8 times farther from the sun than its neighbor "inside." Yes, the difference between the average orbital distance of Mars from the Sun and the average orbital distance of the Earth from the Sun is greater than the difference between the average orbital distance of the Earth from the Sun and the average orbital distance of Venus from the Sun. Since the distance between the Earth and other planets depends not only on the size of their orbits, but also on their relative orbits, Venus is not always closer to the Earth than Mars.
No. It is not the size of a planet which determines how much energy emitted from the sun reaches a planet which is placed in a given orbit.
In the solar system, the planets are arranged sequentially.
Mercury, which is located nearest to the sun, gets the most energy and Neptune, which is located farthest from the sun, gets the least energy.
