Mercury's core has a diameter of about 3,600 miles (5,800 kilometers), which is roughly 85% of the planet's total diameter. It is composed mostly of iron and nickel, and is thought to be partially molten.
Hot and even more hot
Mars, with a diameter 0.53226 times that of the Earth.
Mercury is 4,880 km in diameter, and Uranus is 51,152 km in diameter, so 10.2 mercurys equal the diameter of Uranus.
Mars is about 6780 kilometers (4240 miles) in diameter, a little more than half the diameter of Earth.

The smallest planet in our Solar System is Mercury. The second-smallest is Mars, which has MORE than half of Earth's diameter.
I believe it is Mercury. Mercurys core is 75 percent of its planet. Its core is made of Iron. You might want to do more research though I am not Exactly sure.
The diameter of Mercury is 3,032 miles, or 4,879 kilometers. Mercury is the smallest planet in the Solar System and the closest to the Sun.
Jupiter has the largest diameter (the radius is half the diameter, of course).
The smallest planet in our Solar System is Mercury. The second-smallest is Mars, which has MORE than half of Earth's diameter.

The soil on the planet mercury is grey in color.
Mercury has a diameter of approximately 4,880 kilometers (about 3,032 miles) across its center. It is the smallest planet in our solar system, and its size is roughly 38% that of Earth. Mercury's diameter contributes to its relatively high density, making it one of the densest planets in the solar system.
Dwarf planet Pluto has the moon Charon which is almost half its diameter (2390 km and 1205 km), but Pluto is no longer a planet... The next one is the Earth with the Moon having a diameter 0.273 times the Earth's.
Mercury is 4,880 km in diameter, and Uranus is 51,152 km in diameter, so 10.2 mercurys equal the diameter of Uranus.
