The distance from the Earth to the Sun is more than 149.6 million kilometers, and it takes 8.3 minutes for sunlight to reach the Earth. This means that if the Sun suddenly went out, we on Earth would not notice it until more than eight minutes later. If you drill a tunnel through the Earth and then jump into it, it will take you about 42 minutes to get to the other side. According to accurate calculations, our planet completes a full revolution around its axis in 23 hours and 56 minutes, that is, in fact, a day is somewhat shorter than the generally accepted 24 hours. This also applies to the length of the year, since the revolution around the Sun lasts more than 365 days and 6 hours. That is why every four years another day is added to the calendar (February 29) and we call such a leap year.
