The comoving distance from Earth to the edge of the observable universe is about 14.26 giga parsecs (46.5 billion light-years or 4.40 × 10 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8 × 10 m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22 × 10 Gpc (4.22 × 10 Gly or 3.57 × 10 m).
