Hii,
Thanks, it works properly but for OrthographicCamera we have to do one modification that is we have to divide scale with camera.zoom

var scale = scaleVector.subVectors(planet.position, camera.position).length() / scaleFactor);
var scale = scale/camera.zoom;

Thanks & Regards
Abhijit

If you are using points, you can set sizeAttenuation of the respective material to false.
