Mean solar day is the time interval between two successive noon when sun passes through zenith point (meridian).
Sidereal day is the time interval between two successive transit of a distant star through the zenith point (meridian).
By drawing appropriate diagram showing the earth's spin and orbital motion, show that mean solar day is 4 min longer than the sidereal day. In other words, distant stars would rise 4 min early every successive day.

Explanation

To solve the problem of showing that the mean solar day is 4 minutes longer than the sidereal day, we will follow these steps:

### Step 1: Understand the Definitions
- **Mean Solar Day**: The time interval between two successive noons when the Sun is at its zenith point (meridian).
- **Sidereal Day**: The time interval between two successive transits of a distant star through the zenith point (meridian).

### Step 2: Visualize the Earth’s Motion
1. **Draw the Earth’s Spin and Orbital Motion**:
