It takes approximately 365.25 days for the Earth to orbit the Sun. To convert this to seconds, we can use the following calculation:

* Days in a year: 365.25 days

* Hours in a day: 24 hours

* Minutes in an hour: 60 minutes

* Seconds in a minute: 60 seconds

Therefore:

365.25 days * 24 hours/day * 60 minutes/hour * 60 seconds/minute ≈ 31,557,600 seconds

So it takes approximately 31,557,600 seconds for the Earth to go around the sun.
