1 E+23 m²

To help compare orders of magnitude of different surface areas, we list here examples of areas of the order of 10²³ square metres, i.e. those between 100 quadrillion km² and 1 quintillion km². See also areas of other orders of magnitude.

Areas smaller than 100 quadrillion km²
- 1 E+23 m²
- 1.6 · 10²³ m² — area swept by Mars' orbit around Sun
- 2.81 · 10²³ m² — surface area of a Dyson Shell with a radius of 1 AU.
Areas larger than 1 quintillion km²
