You are on the surface of an object, and you have a fairly clear view out into space. Unfortunately, you are also very squashed. The light you observe from distant objects is slightly blueshifted.
The surface of the object is composed primarily of carbon and oxygen, and the distance to the horizon seems about the same as that on Earth. By observing the sky for a few weeks, you realize that there are several planets orbiting your object. Where are you?
A) You are on the surface of a neutron star.
B) You are on the surface of the Earth.
C) You are on the surface of a planet that is somewhat more massive than the Earth.
D) You are on the surface of a white dwarf.
E) You are on an accretion disk around a black hole.
