Here’s the orbital period of our solar system’s 8 major planets (how long it takes each to travel around the sun). Their size is to scale and their speed is accurate relative to Earth’s. The repetition of each GIF is proportional to their orbital period. Mercury takes less than 3 months to zoom around Sol, Neptune takes nearly 165 years.
Actually, Earth completes its orbit around the Sun in 365 and ¼th Earth days. So technically at 6am on January 1st, a whole orbit around the Sun would be complete just for that year, each following year the orbit would be decreased by ¼th day, making it ½ day and 3/4th day. But since we do not have it that way in the calenders, we disregard that ¼th day(and so on) and continue to live as if the next common year starts. That’s where we get leap year from. Leap year is composed of that disregarded ¼th day from the previous 4 years. Then the cycle starts over. So this information is very close, but is not accurate.
