That's very small for a planet!Planets have diameters measured in thousands of kilometers. I think you may have used the wrong number.
22km long.
To calculate the diameter of a planet, you can use the formula for the diameter based on the planet's radius: Diameter = 2 × Radius. If you have the planet’s circumference, you can also calculate the diameter using the formula: Diameter = Circumference / π (where π is approximately 3.14). Additionally, if you have access to images or data from space missions, you can use measurements of the planet's shadow or transit across a star to estimate its size.
The planet Uranus.
The planet you are referring to is Jupiter, which has a diameter of approximately 86,881 miles. Mercury has a diameter of about 3,032 miles, Venus has a diameter of about 7,521 miles, Earth has a diameter of about 7,917 miles, and Mars has a diameter of about 4,212 miles.
Jupiter is the largest with the largest diameter.
the Jupiter diameter is 142,984km
Uranus is third largest. Diameter = 51115km, about 8 times that of Earths diameter.
Mercury is the smallest planet, so there isn't one with half the diameter.
About 22km
The largest planet in the solar system is Jupiter, with a diameter 11.209 times that of the Earth
Mercury is the only planet in our solar system that is less than 3000km in diameter, with a diameter of about 4879 km.
It's Olympus mons on the planet mars. It is nearly 22km (14 miles) high when compared to the surrounding plains. The planets lower gravity means that this volcano has remained high when compared with mountains on our own planet.
