The mean distance between the Earth and Sun as well as the distances within the solar system is represented by

Options

A. Light year
B. Astronomical units
C. Parsec
D. Angstrom

Answer

To solve the question regarding the mean distance between the Earth and the Sun, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept**: The question asks for the term that represents the mean distance between the Earth and the Sun, as well as distances within the solar system.

2. **Identify the Term**: The standard term used in astronomy for this mean distance is the "Astronomical Unit," abbreviated as AU.

3. **Know the Value**: One Astronomical Unit (1 AU) is approximately equal to 93 million miles. This value helps to understand the scale of distances in the solar system.

4. **Select the Correct Option**: Based on the information that 1 AU represents the mean distance from the Earth to the Sun, we can conclude that the correct answer to the question is "astronomical unit."

### Final Answer:
The mean distance between the Earth and Sun, as well as the distances within the solar system, is represented by the **Astronomical Unit (AU)**.
