The year-long orbit of the Earth around the sun now takes 365 days, 6 hours, 9 minutes and 10 seconds. For simplicity, we can call that 365 and a quarter days. This means that, if you celebrate New Year’s Eve after a year of 365 days, the Earth still has a quarter of a day of movement before you’ll be back to exactly where you were last New Year’s Eve. The Earth is tearing around the sun at a speed of around 30 kilometres every second, so this New Year’s Eve you will be over 650,000 kilometres away from wherever you were last year.
