- Homework Statement
- 1. Consider the sun like a star at a distance of 2 parsecs. When it is seen through a telescope with 100 magnification, what should be the angular size of the star? Sun appears to be (1/2)° from the earth. Due to atmospheric fluctuations, eye cannot resolve objects smaller than 1 arc minute.
OR
Moon is seen to be of (1/2)° diameter from the earth. What must be the relative size compared to the earth?
- Relevant Equations
- I know that one parsec is the angle at the vertex which subtends an arc with length 1 AU.
What is the image that comes to mind/meaning behind the above statements where an objects is seen/appears 'to be (angle) diameter of the Earth?
My interpretation is that if the given angle is drawn with one object as the vertex then the diameter of the second object subtends the given angle.(?)
