Yes, everything has matter
Your answer is going to be letter B
Using Kepler's 3rd Law of planatary motion we know that the sqare of the orbital period is proportional to the cube of the semimajor axis.
So we know the earth is 1 AU from the sun with a period of 1 year so we can set up a ratio as follows:
P^2 / r^3= 1
(P)^2 = 4^3
<span>P = 4^(3/2) = 8 years </span>
