| Question | Answer |
| If the parallax angle is one arcsecond (1") the distance to the star is called a PARSEC | d (parsecs) = 1/p (p in arcsecs) |
| Converting degrees to arcsecs in radians STEP 1 | STEP 1: Multiply by 2pi/360 to convert to radians |
| Converting degrees to arcsecs (in radians) STEP 2 | STEP 2: Multiply by 1/3600 to convert to arcsecs |
