The distance between the Sun and Earth is approximately 1 astronomical unit (AU). An astronomical unit is defined as the average distance from the Earth to the Sun, which is about 93 million miles (or about 150 million kilometers).
To convert this distance into light-years, we need to know the speed of light, which is about 299,792,458 meters per second or approximately 186,282 miles per second. In one year, light travels approximately 5.88 trillion miles (about 9.46 trillion kilometers).
Therefore, the distance between the Sun and Earth in light-years can be calculated as follows:
1 AU ≈ 93 million miles ≈ 150 million kilometers 1 light-year ≈ 5.88 trillion miles ≈ 9.46 trillion kilometers
So, to calculate the distance between the Sun and Earth in light-years:
Distance = (1 AU) / (5.88 trillion miles) Distance = (1 AU) / (9.46 trillion kilometers)
Using these conversions, the distance between the Sun and Earth is approximately 0.0000159 light-years (or about 0.0000256 light-years)
