The parallax of a heavenly body measured from tow points diametrically opposite on equator of earth is 2.0 minute. If radius of earth is 6400 km, calculate distance of heavenly body.

Explanation

To solve the problem of calculating the distance of a heavenly body based on its parallax measured from two points on the Earth's equator, we can follow these steps:

### Step 1: Convert the parallax angle from minutes to radians
The parallax angle given is 2.0 minutes. We need to convert this into degrees first and then into radians.

\[ \text{Parallax angle in degrees} = 2.0 \text{ minutes} \times \frac{1 \text{ degree}}{60 \text{ minutes}} = \frac{2.0}{60} \text{ degrees} \]
