Question

How much time does the earth take to revolve around the sun?
A) 360
B) 365
C) 368
D) 370

Answer 1

Hint: The time taken by earth to revolve around the sun is known as year 24 hours are taken to complete one rotation around itself. A leap year has 366 days.

Complete answer:
One revolution around the sun takes the Earth 365 days and 6 hours to complete. That's why 365 days a year but a leap year with 366 days after four years means that by multiplying times, the 6 hours increased to one day. It implies that 6 hours over 4 years is equal to 1 day.

The time taken by Earth to complete one revolution around the sun is defined as a solar year. For the sake of simplicity, this solar year, as stated in the calendar, is taken to be 365 every year. This is not the total truth, however. 365.2421891 days, almost an extra quarter of a day is the time taken by Earth to complete one complete revolution. Our calendar does not account for each year for that quarter of the day but accounts every four years for the lost time and calls it a leap year. We delay the month of March by one day after adding an additional day to the month of February to do so.

Hence the correct answer is option ‘B’.

Note:
i) The average distance is 149.60 million km between the Earth and the Sun (92.96 million mi),
ii) Earth travels 940 million km (584 million mi) in 365.256 days.
iii) Earth takes 365.2421891 days, almost a quarter extra day to complete one complete revolution. Our calendar does not account for each year for that quarter of the day but accounts every four years for the lost time and calls it a leap year.
