1 E+40 m³

To help compare the orders of magnitude of different volumes, here is a list of volumes between 10⁴⁰ m³ and 10⁵⁰ m³. See also volumes or capacities of other orders of magnitude and corresponding lengths.

• Smaller volumes than 1 E40 m³

The Cat's Eye Nebula on left (about 3×10⁴⁶ m³) and the dark cloud Barnard 68 at top (about 6×10⁴⁶ m³) are of comparable volumes; the Stingray Nebula between them is smaller with a similar volume as the small yellow light-month radius sphere, about 2×10⁴⁵ m³.

1 E+40 m³ to 1 E+43 m³

• 1.1×10⁴¹ m³ = daily increase in volume of the Cat's Eye Nebula^[1]

1 E+43 m³ to 1 E+46 m³

• 4×10⁴³ m³ = annual increase in volume of the Cat's Eye Nebula^[1]

• 2×10⁴⁵ m³ = approximate volume of the Stingray Nebula^[2]

1 E+46 m³ to 1 E+49 m³

Planetary nebula typically have volumes in this range.

• 2.7×10⁴⁶ m³ = volume of the Cat's Eye Nebula^[1]
• 5.5×10⁴⁶ m³ = the volume of a Bok globule like Barnard 68^[3][4]

• 4.4×10⁴⁷ m³ = the volume of a Bok globule one light year across^[3][4]
• 8.47×10⁴⁷ m³ = 1 cubic light-year

• ~1.7×10⁴⁸m³ = volume of the Oort Cloud, assuming a radius of 50000 AU

1 E+49 m³ and larger

• 2.93799894×10⁴⁹ m³ = 1 cubic parsec

• Larger volumes than 1 E50 m³
