B. They are smaller in size.
C. They have less distance to travel for one revolution.
D. They have longer seasons

Answer 1

Answer:

D They have longer seasons

Explanation:

I think this because the days will be longer so that means that the seasons will change also.

Answer 2

Answer:

A.They have longer periods of revolution.                      

Explanation:

From Kepler's law, we understand that:

• The planets revolve about the Sun in elliptical paths with Sun at one foci.
• Equal areas is swiped in equal interval of time.
• Closer the planet, faster it moves.

Thus, planets which have longer orbits that is are farther from the Sun have longer periods of revolution. This can be directly inferred from Kepler's third law.

P² ∝ a³

where, P is the period and a is the semi-major axis.
