The circumference of Mercury at equator is 15 329 km.
The circumference at the equator is 15 329 km for the planet Mercury.
Mercury's diameter is about 4875 kilometers, at the equator. The circumference is "pi" x 4875. That's about 15315 kilometers.
Mercury
Yes. Mercury rotates, like all the planets. So it has an axis of rotation and that defines the "poles" of the planet. The equator is defined relative to the planet's poles.
Mercury's Inclination of it's equator to it's orbit is 0 degrees. The answer is Mercury
It's about 2440 kilometers. Mercury is almost spherical, so the radius is about the same everywhere.
4879 km at its equator or 3031 miles long
At the equator, the surface temperature on Mercury (facing the sun) can reach 700K (430'C).
The diameter of Mercury is 4879 km at its equator, or 3,031 miles.
The planets in our solar system vary widely in size and diameter at the equator. For example, Earth's diameter at the equator is about 12,742 kilometers (7,917 miles), while Jupiter's diameter at the equator is about 142,984 kilometers (88,846 miles). The smallest planet, Mercury, has a diameter at the equator of about 4,880 kilometers (3,032 miles).
Mercury is not the largest of the planets in the solar system. It is the smallest planet. The biggest planet in the solar system is Jupiter, which is about 143,000 kilometers wide at its equator.
