The nearest star to our solar system is 4.29 light year away. How mush is this distance in terms of parsec? How much parallex would this star show when viewed from second location of earth 6 months apart in its orbit around the sun? Can you please explain it with a diagram.

Expert Answer:

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

The star when viewed from one position of Earth appears at a different location 6 months later.

The angular shift in the star's position is the parallax of the star given as θ.

Hence, we have

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
