How many trips has earth made around the sun in 8 mars years?

15 Trips

Explanation:

Mars is known as one of the highest eccentricities of any planet in solar. They range from 2.6 million and 2.4 million. The tilting of the earth occurs because of the obliquity of the ecliptic. The axis of the earth tilts in 23.4 degrees to the sun towards the plane where the sun travels. Assumingly the axis of the planet keeps tilting in the same spot. Therefore during summer, the northern hemispheres appear high in the sky in the day time.

According to the question,

1 year in Mars = 687 days in Earth

Thus,

8 years in Mars = days in earth

Thus,

5496 days in Earth = years in earth

Thus, earth takes around 15 trips around the sun in Mar's 8 years.
