Estimate how many years it takes Mars to orbit the Sun - AQA - GCSE Physics - Question 4 - 2018 - Paper 1

Mars takes approximately 687 Earth days to complete one orbit around the Sun. To convert this into years, we can use the following calculation:

ext{Years} = rac{ ext{Days}}{365} = rac{687}{365} \approx 1.88 ext{ years}

Thus, it takes Mars about 1.88 years to orbit the Sun, which we can round to approximately 2 years.
