It Takes Our Solar System ____ Years to Rotate Around the Milky Way.
A
400 million
B
400 billion
C
225 billion
D
225 million
Explanation: 

Detailed explanation-1: -Yes, the Sun-in fact, our whole solar system-orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828, 000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way! The Milky Way is a spiral galaxy.

Detailed explanation-2: -At our sun’s distance from the center of the Milky Way, it’s rotating once about every 225-250 million years – defined by the length of time the sun takes to orbit the center of the galaxy.

Detailed explanation-3: -The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. One galactic year is 230 million Earth years.

Detailed explanation-4: -The rotational period is about 212 million years at the radius of the Sun. The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference.
