The Earth is 93 million miles (150 million kilometers) away from the Sun. It is average distance because Earth orbit is elliptical. The speed of light in a vacuum is 300,000 km/s so the light travel approximately about 8 minutes (more exactly: 499 seconds)

The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The half-Life of Iodine

The duration of pregnancy in humans is about 40 weeks (280 days, equal to 9 calendar months) from the date of the last menstrual period.

A sidereal year is the time taken by the Earth to orbit the Sun once with respect to the fixed stars. It equals 365.256363004 days (for the epoch J2000.0). That is 365 days 6 hours 9 minutes 9.76 seconds.

The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value The half-life of Carbon

Modern geologists and geophysicists consider the age of the Earth to be around 4.54 billion years (4.54 × 10
