WebSo, solving the distance formula for h , we have: h = d 2 (1 − k ) / 2R . And as this is just the difference between H H and H obs, we find that H H = H obs + h . But, as every point on OH appears at the observer's astronomical horizon, in particular the point H is seen on that horizon; so its altitude is exactly zero.
