Neither Sirius A nor Sirius B have any known planets.
Uranus' moons are located at varying distances from the planet. The closest moon, Cordelia, orbits about 49,800 kilometers away from Uranus, while the farthest moon, Sycorax, orbits around 20.5 million kilometers away.
no their is no planet which is very far away from the sun but in the past pluto was very far and small thats why it had not been counted as a planet
It is not clear that Pluto has been pushed anywhere, it is a large Kuiper belt object with an orbit that is not in the plane of the other the Solar System's planet orbits which indicates it is orbiting where it always did. It is Uranus and Neptune that have moved out in their orbits.

Io orbits at a radius of about 421,700 km from Jupiter
No, the distance of a planet from the sun is determined more by its orbit and gravitational interactions with other celestial bodies rather than its mass. The mass of a planet does affect its gravity, which in turn influences its orbit, but it is not the sole factor determining its distance from the sun.
How far away is Pluto from all the pther planets?
No. The planets in the Solar System all have almost circular orbits, but the orbits of comets are highly eccentric (oval-shaped). This means that while the distance a planet is from the Sun is rather constant, the path of a comet means it comes close to the Sun, and then moves far away.
There is no planet astronomers here on Earth call "nester". So if there is one it is very far away (in space and time)
It is not that far away. The asteroid belt lies between the orbits of Mars and Jupiter.
5,890,000,000 km
it is approximately 387,000,000 km away
