Answer:
The Earth's orbit is approximately 940 million kilometers (km) or 584 million miles (mi) long, and it is constantly changing due to gravitational forces from other celestial bodies. However, converting this length to millimeters (mm) would require multiplying the number by 1 billion (1,000,000,000), since there are 1 billion millimeters in a kilometer. Therefore, the length of the Earth's orbit in millimeters is:
940,000,000 km x 1,000,000,000 mm/km = 9.4 x 10^17 mm (in scientific notation)
This number is very large, so to give an idea of its magnitude, it can also be expressed as 940 quadrillion millimeters or 940 million billion millimeters.
