# Do any coordinate systems include self magnification?

• A
Take a neutron star, its surface will be gravitationally self magnified so that it looks bigger to the distant observer, than it 'really' is, plus you can see some of the rear facing surface.

If you take the centre of the neutron star, then this process must go on there also, although unseen.

I was wondering if any coordinate system incorporated this process, say by building the shape of space from the inside of the neutron star, outwards, as the distant observer might 'see' it..?

From the center of the neutron star the neutron star occupies 360 degrees same as center of Earth. From the surface of the neutron star the neutron star occupies 180 degrees same as surface of Earth. You could see stars that should be over the horizon.

a distant observer can see more than 50% of the neutron star's surface.
