Jupiter is the largest planet and therefore has the largest radius. The radius of Jupiter is 43,441 miles (69,911 kilometers).
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
Neptune with an equatorial radius of 24,764 about 3.88 that of the Earth [See Link]
Jupiter is the largest planet, with an equator radius of ~71,492km and polar radius of ~66,854km. Jupiter also has a huge mass, which is 2.5 times that of all the other planets in our solar system put together!
Planet X has not been confirmed to exist, so its size is unknown. Jupiter is the largest planet in our solar system, with a radius of about 69,911 km.
The largest object in space that is not a planet or a star is a galaxy. Galaxies are massive systems of stars, gas, dust, and dark matter held together by gravity. They can contain billions to trillions of stars and are among the largest known structures in the universe.
Jupiter is that planet.
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
Jupiter has the largest diameter (the radius is half the diameter, of course).
Saturn has a radius of 36,184 miles (58,232 kilometers). This makes Saturn the second largest planet in the Solar System, after Jupiter.
Neptune with an equatorial radius of 24,764 about 3.88 that of the Earth [See Link]
That would be Uranus. Uranus has a diameter of about 51,000km, making it the third largest planet in terms of radus/diameter/volume etc. but it's mass is only 15 times that of Earth, less than Neptune, making it the fourth largest in terms of mass.

This is nothing to do with planets. It's part of the theory of black holes. Perhaps you mean if the planet's mass were concentrated into a black hole. In that case the answer is Jupiter, because it has the greatest mass.
No. Kepler-22b is between the sizes of Earth and Neptune. The largest known planet is HAT-P-32b which gas about twice the radius of Jupiter.
Jupiter is the largest planet in the solar system with a 71,492 mile equatorial radius (11.209 times larger than the earth).
Uranus is the 3rd to largest planet.
Its the third-largest and fourth most massive planet in the solar system.sources:http://en.wikipedia.org/wiki/Uranus
