Orders of magnitude (one cubic gigametre and greater)

The following is a table of objects with volumes or capacities of one cubic gigametre or greater.

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.
The Bubble Nebula (NGC 7635) at left with about 520 cubic light years (4.4×1050 m3) dwarfs the Dumbbell Nebula's 12 cubic light years (1×1049 m3). (very approximate figures)
The globular cluster Messier 5 at upper left with about 2 million cubic light years (1.7×1054 m3) dwarfs the much smaller Bubble Nebula at lower right.
