No planet in the solar system has that diameter.
The smallest planet, Mercury has a diameter of 4,879.4Km
Have you mixed up diameter with radius? If so, Mars is the closest with a radius of 3,396.2km.
As you didn't specify a unit of measurement, I'm going for Km.
The Moon has an equatorial diameter of 3,476.28 km - so close enough.
Jupiter has that diameter, at its equator.
You must be thinking of Saturn. Its polar diameter (up and down) is about 108,700 km,
and its equatorial diameter (side to side) is about 120,500 km.
Four planets qualify, depending on how close you want the diameter to be to 50,000 km.
None. The smallest planet is Mercury; it has a diameter of about 4900 km.
The radius of Mars is 3397 kilometers. The circumference of Mars at the equator is about 21,343 kilometers.
Jupiter is the largest planet in the Solar System, having a diameter of 142,984 km at its equator. 142,984 Kilometers = just over 88,846 Miles
The diameter of the Moon is 2159 miles or 3474 kilometers.
The equatorial diameter is about 12,104 miles, or about 95% of Earth's. (More precisely 12103.6 km.) This is also the polar diameter since Venus's very slow rotation does not produce any significant bulge of the equator as on the other, rapidly rotating planets.
Ceres, not Cene, is a dwarf planet that is the largest object in the asteroid belt. It is 950 kilometers in diameter.
The diameter of mars = 6794 kilometers
Jupiter's diameter is 88,800 miles (143,000 kilometers).
Mercury is the smallest planet with a diameter of 4879.28 kilometers.
Earth's diameter is approximately 7,920 miles (12,700 kilometers).
142800 km = 88730 miles, approx.142800 km = 88730 miles, approx.142800 km = 88730 miles, approx.142800 km = 88730 miles, approx.
Pluto's diameter is about 2,400 Kilometers.
Answer: 142800 km = 88,731.806 mi.
The diameter of Venus is 7,521 miles. This is the same as a diameter of 12,104 kilometers. Venus is the second planet from the Sun.
Venus has a diameter of 7,521 miles, or 12,104 kilometers. It has a circumference of 23,628 miles, or 38,025 kilometers.
Mercury is the closest planet to the Sun. It has a diameter of 3,032 miles, or 4,879 kilometers. It is the smallest planet.
Mercury is far smaller with a diamter of about 2,400 kilometers. It is the smallest planet in the solar system while Jupiter is the largest with a diameter of about 70,000 kilometers.
Mars is about 6780 kilometers (4240 miles) in diameter, a little more than half the diameter of Earth.
