by using the position on the sky and the redshift to determine a distance along the line of sight
The universe was really three-dimensional, and instead of thinking of circles, he should be thinking about spheres, with the planetary orbits being along the equators

That MIGHT refer to the Universe; however, it is not currently known whether its size is actually finite or infinite.

The set of Pythagorean triple is three dimensional and infinitely large.
For two or three hundred years, astronomers have had a fair idea the the Sun is not the center of the Universe.
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
A sphere is indeed a three dimensional shape. It is a circle rotated about an axis several times to create and three dimmensional object from a two dimensional shape.

the answer really is 6there are 6 faces in a three-dimensional model
