Parallax angle question

if a star is 5.2x1016 meters away, what is the parallax angle in degrees?

Just need a step by step answer to confirm that my answer of 0.000165598290 is correct ( note that the second five and zero have a recurring symbol above each)

I used the conversion 1parsec= 3.1x1016m in my calculation

any help would be much appreciated

Hi Heisenberg28,1. 1 parsec=3.1x1016m, so the distance is 5.2/3.1=1.68 parsecs2. Rearrange distance=1/parallax angle to give parallax angle=1/distance    3. Parallax angle= 1/ 1.68=0.60 sec4. 1 sec =1/3600 degree, so in degrees, parallax = 0.60/3600= 0.000167degrees5. so you are correct, just need to use less significant figures...
