The angular diameter in arc seconds of the neutron star be as seen from Earth is 18.22 arc seconds.
Angular diameter of the neutron star
The angular diameter of the neutron star is calculated as follows;
[tex]\frac{angular \ diameter }{2.06 \times 10^5 \ arc \ seconds} = \frac{linear \ diameter}{distance} \\\\angular \ diameter = 2.06 \times 10^5 \ arc \ seconds(\frac{linear \ diameter}{distance})[/tex]
- linear diameter of neutron star = 2 x 17 km = 34 km
- distance between Earth and moon = 384,400 km
angular diameter = 2.06 x 10⁵ x (34/384,400)
angular diameter = 18.22 arc seconds
Thus, the angular diameter in arc seconds of the neutron star be as seen from Earth is 18.22 arc seconds.
