2 AU
Figure 2.1: Parsec into Km. In the figure B and C are two diametrically opposite positions of the Earth while
it revolves around the sun. The star is located at point A and S is the Sun.
Transcribed Image Text:2 AU Figure 2.1: Parsec into Km. In the figure B and C are two diametrically opposite positions of the Earth while it revolves around the sun. The star is located at point A and S is the Sun.
Problem 1. In this problem we calculate how many Km are there in 1 pc. In Figure 2.1, ZSAB = 0 = 1
arc-sec
1. First convert this angle into radians. Given that 1° = 60 arc-min, 1 arc-min = 60 arc-sec and one radian
is equal to 180/7 degrees.
2. Since this is a very small angle as compared to 1 radian, so we can use tan0 = BS/AS≈ 0. Knowing
BS = 1 AU, calculate AS.

Expert Solution
Step 1

We know, 

1° = 60 arc-min

1 arc-min = 60 arc-sec

1° = π/180 radian
