It's about one-seven-hundred-thousandth as long as The Distance from Earth to the Moon.
In other words, 0.540 kilometers is 0.0000014046530 times the length of The Distance from Earth to the Moon, and the length of The Distance from Earth to the Moon is 711,919.60 times that amount.(a.k.a. Luna) (median of semi-major axis, or apigee, and semi-minor axes, or perigee)
The orbit of the Moon around the Earth is elliptical, with an average distance of 384,436.5 km from center-to-center. About 428.376 kg of moon rock have been cataloged on the Earth, from the American Apollo and Soviet Luna Programs, and from samples that have been extracted from meteorites.

It's about 70,000,000 times as long as a Red Blood Cell.
In other words, 0.540 kilometers is 72,000,000 times the length of a Red Blood Cell, and the length of a Red Blood Cell is 0.0000000140 times that amount.(a.k.a. RBCs, a.k.a. haematids, a.k.a. erythrocyte, a.k.a. erythroid cells, a.k.a. red blood corpuscles) An average Red Blood Cell measures 7.5 µm (micrometers) in diameter. An average human has 20 - 30 trillion red blood cells in their body and each cell completes a circulatory lap in about 20 seconds.
It's about 90,000,000 times as long as a Nucleus (Cellular).
In other words, the length of a Nucleus (Cellular) is 0.0000000110 times 0.540 kilometers.(for animal cell)
The nucleus of an animal cell measures an average of 0.00000000600 kilometers. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
