It's about 0.00000004 times as long as The Circumfrence of Earth
In other words, 0.0017 kilometers is 0.0000000424204470 times the length of The Circumfrence of Earth, and the length of The Circumfrence of Earth is 23,573,538 times that amount.(Equatorial)
The Earth — not a perfect sphere, but rather an oblate spheroid with bulged middle — has an Equatorial circumference of approximately 40,075.014 kilometers. The first airplane trip around the circumference of the Earth (with a few stops along the way), was completed in 1924 by the United States Army Air Service, and took 175 days.
It's about 0.000000005 times as long as The Distance from Earth to the Moon
In other words, 0.0017 kilometers is 0.0000000044220570 times the length of The Distance from Earth to the Moon, and the length of The Distance from Earth to the Moon is 226,139,100 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 1,000,000,000 times as wide as a Glucose Molecule
In other words, 0.0017 kilometers is 1,100,000,000 times the width of a Glucose Molecule, and the width of a Glucose Molecule is 0.000000000910 times that amount.(C6H12O6, a.k.a. grape sugar) (open chain form)
Am individual glucose molecule measures 0.00000000000150 kilometers in its open-chain form. Glucose is the most common fuel source of energy in human biology, with 3.75 kilocalories of energy per gram.
