What get the most sunlight?

Answer 1

More solar radiation reaches Jupiter than any other object, because it occupies more of the sun's "field of vision" than any other object. In other words, as seen from the sun, Jupiter "looks biggest," as a near-circle whose average diameter spans an angle of 37 arcseconds.

Here is a list of the planets in order by average apparent size as seen from the sun:

1. Jupiter (37.04 arcseconds)
2. Venus (23.07 arcseconds)
3. Earth (17.57 arcseconds)
4. Mercury (17.38 arcseconds)
5. Saturn (17.34 arcseconds)
6. Mars (6.13 arcseconds)
7. Uranus (3.67 arcseconds)
8. Neptune (2.27 arcseconds)
