is the math correct?

57.3 x d_o/d
d_o = size of object which is 1.392 x 10^6 km
d = distance to the object which is 147,056,800 km (Perihelion)
57.3 x 1.392 x10^6 (1,392,000) / 147,056,800km
= .54 Degrees


?

Thanks

hi nukeman! :smile:

(try using the X2 icon just above the Reply box :wink:)

Yes, angle = (size/distance) radians,

and 1 radian = 57.3°

so angle = (size/distance) times 57.3° :wink:
