Final answer:
The sun is about 93 million miles from Earth as a whole number, which translates to 1.5 × 10¹± meters or 150 million kilometers, and is also referred to as 1 astronomical unit (AU).
Step-by-step explanation:
The distance from the Earth to the Sun is approximately 93 million miles when written as a whole number. This distance can also be expressed in scientific notation as 1.5 × 10¹± meters, which is equivalent to 150 million kilometers. Astronomers use astronomical units (AU) to measure this distance, with 1 AU representing the average Earth-Sun distance. Converting between measurements is a common practice in astronomy due to the typically large distances involved.
