The star GJ 1156 has a parallax angle of 0.153 arcsec. How far away is the star?

Answer 1

Leah Abbate

d = 6.53 parsecs.

The distance in parsecs is inversely proportional to the parallax, which is given in arcseconds.

thus,

d is equal to 1/p.

The value of p is 0.153 arcsec.

d is equal to 1 /0.153.

d is equivalent to 6.53 parsecs.

Using the formula Distance (in parsecs) = 1 / Parallax angle (in arcseconds) yields the following result: Distance = 1 / 0.153 = 6.54 parsecs.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
