The Earth's Geo Corona
Below, the reader will find an image from the Dynamics Explorer - 1 satellite from the year 1981. The image shows the radius of the inward sloping portion of a crater with a gradual slope. We hollow earthers allege that there is an orifice at the center of this crater which penetrates into the Earth's inner cavity, a hollow world.
First of all, the reader will see that The Sun's rays are striking the planet at a slight angle towards the North; in other words, the planet is ever so slightly nodding its head and tipping its hat towards The Sun. This exposes the far side of the concave crater opening to The Sun's rays, and has created a shadow starting from the side wherefrom The Sun shines. In order to understand the shape of this opening, and of the polar extremes of our planet, the reader can think of the top of an apple where the stem is; but in this case hollow earthers allege that there is an orifice at the bottom, in the center, as an hourglass has at its neck. So we can refer to this gradually sloping crater at the top of the world, with its orifice at the center-bottom, as an hourglass opening.
As far as the radius of the crater/hourglass opening is concerned; it encompasses most all of the Arctic ocean, certainly as far East as the northern tip of Greenland. We cannot see the slope nor the orifice at the center of the hourglass opening because of the long shadow cast across its concave shape but, from the accelerated sledding speeds reported by Dr. Cook as he made an attempt at discovering the North Pole - and Robert Peary, who was credited with having discovered it - we can assume that at the center, the slope becomes more inwardly sharp, as an apple does at the base of its stem.
We can also understand that, thanks to the slope, a person standing at some point in the middle of the inward slope would be so off-kilter and slanted, that the person's head would point towards the Polestar, although the person would not be under it. This concept is more fully explained and diagramed on our Curvature Anomalies page:
I invite the reader to study the satellite image and scroll further down in order to become better informed about the origin and authenticity of the image, and then pass over to the Curvature Anomalies page.

Source of Images and Caption Information
The image in the left panel shows an active auroral oval on 14 October 1981 at 2017 UT following the onset of a substorm at local midnight. Spacecraft altitude is 16,500 km at 67° N latitude. The image in the right panel provides a view of Earth's dark hemisphere at 0222 UT on 16 February 1982 while the sun is behind Earth. Spacecraft altitude and latitude are 19,700 km and 13° N, respectively. The northern auroral oval forms a halo of light above the limb of Earth, while the equatorial airglow bands in the premidnight sector straddle the magnetic equator. Isolated points of light in both images are VUV bright stars.
