Which planets diameter would be approximately the distance across the United states

The diameter of the planet Earth is approximately 12,742 kilometers (or 7,918 miles). The distance across the United States from the East Coast to the West Coast is approximately 4,960 kilometers (or 3,092 miles).

Therefore, no planet in our solar system has a diameter that is roughly equivalent to the distance across the United States.

The approximate diameter of the Earth is about 7,917.5 miles (12,742 kilometers). The distance across the United States, from the easternmost point in Maine to the westernmost point in Alaska, is about 2,800 miles (4,500 kilometers). Therefore, the diameter of Earth is significantly larger than the distance across the United States.

To determine which planet has a diameter approximately equal to the distance across the United States, we need to find the diameter of the United States and compare it with the diameters of different planets in our solar system.

The distance across the United States can vary depending on the specific points chosen, but on average, the distance from the east coast to the west coast is approximately 4,989 kilometers (3,104 miles).

Now, let's compare this distance to the diameters of the planets in our solar system:

- Mercury: Diameter of 4,879 kilometers (3,032 miles)
- Mars: Diameter of 6,780 kilometers (4,212 miles)
- Venus: Diameter of 12,104 kilometers (7,521 miles)
- Earth: Diameter of 12,742 kilometers (7,918 miles)
- Uranus: Diameter of 51,118 kilometers (31,763 miles)
- Neptune: Diameter of 49,528 kilometers (30,775 miles)
- Saturn: Diameter of 116,464 kilometers (72,367 miles)
- Jupiter: Diameter of 139,820 kilometers (86,881 miles)

From the comparison, we can see that the diameter of the Earth is the closest to the distance across the United States. Therefore, Earth is the planet that has a diameter approximately equal to the distance across the United States.
