To help compare sizes of different surface areas, we list here areas between 1018 square metres and 1024 square metres, i.e. those between 1 trillion km² and 1 quintillion km².
Smaller areas
1 E+18 m2
- 1 trillion km² is equal to:
- 1 E+18 m²
- 1 square gigameter
- 6,100,000 million km² -- surface area of the Sun
1 E+19 m2
1 E+20 m2
1 E+21 m2
1 E+22 m2
- 1.1 · 1022 m² - area swept by Mercury's orbit around Sun
- 3.7 · 1022 m² - area swept by Venus' orbit around Sun
- 7.1 · 1022 m² - area swept by Earth's orbit around Sun
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.
